You could try 0.5mg before bed, increasing to 1mg then 2mg if necessary.You should really take prazosin 3 times a day if you want to glean an anxiolytic effect during the day. I started at 1 mg t.i.d. Dizziness was a problem at first, but it mitigated within a week. I am now taking 6 mg/day. It is a very clean drug.

Hi Ed.
I checked out a few studies on Google.
You are right. Some people respond well to dosages as low as 1 mg h.s. I wouldn't have thought so. Some people go to 6 mg and higher, though.
I don't know how you do it. I really don't.
You are amazing. I don't know how you can keep all of this important information and wonderful insights in your head.

> My sleep is significantly smoother for having added prazosin. I experience fewer awakenings. Experiments have shown that prazosin and clonidine each increase the spectral power of delta-wave (slow-wave) sleep as seen on an EEG. This should produce a greater period of time spent in deep sleep. I hope prazosin helps you.
Speaking of polypharmacy, if prazosin helps, but is not wholly adequate, you can add clonidine to augment the prazosin. I don't know if anyone has tried this for PTSD, but it makes sense to me. If taken at night along with prazosin, any tendency towards dizziness might dissipate by morning. I'm not sure. Both clonidine and prazosin are used to treat hypertension. I don't know if the two drugs are synergistic with respect to lowering blood pressure. By the way, at 6 mg/day of prazosin, my blood pressure while seated is normal (120/76). I experience some mild to moderate orthostatic hypotension. Note that I am taking Parnate at the same time, which, itself, causes dizziness.
Topamax is also good for treating PTSD, just in case you are thinking along those lines. I don't know if it affects sleep architecture at all.

Very kind of you Scott.
I was thinking that Sigi does not like anything which makes him feel 'off' during the day. Taking prazosin as a single dose at night might improve sleep whilst avoiding daytime adverse effects. Disturbed sleep seems to be one of Sigi's main problems.

No, it's my problem as well. I certainly didn't mean to insult you. I'm sorry.

Just to let you know, Some people with PTSD go as high as 12 mg/day with prazosin. The maximum recommended dosage is 20 mg, although some people go up to 40 mg. There is a lot of room to work with. Like I said, prazosin is a clean drug for me. At 6 mg/day, I experience no alterations in mental function. There is no "brain-fog" or sense of feeling "drugged". For the first 1 - 2 weeks, you might feel some fatigue and tiredness along with dizziness. However, these things might not surface if you start at 1 mg at night.
I understand that sleep is a an issue with you, and you can limit your intake of prazosin to a night dose. However, if anxiety and depression are problems during the day, you could take prazosin three times a day.
My only complaint is that prazosin reduces my sex drive. I was not happy about this, as depression all but abolishes it. I'm hoping that I recover some of it as I improve. I do experience occassional dizziness, but I am taking Parnate, which is known to do this on its own.
Prazosin has a short half-life (2-3 hours). That's why it is recommended to dose it two or three times a day to treat hypertension or daytime PTSD. If you should want to stop taking prazosin, it will take a day or two for it to completely leave your system.

>My only complaint is that prazosin reduces my sex drive.
Well I read that it can induce priapism, a mild dose of which would have been most welcome, but I did not experience this myself.
My sleep was greatly improved by 0.5mg. When I woke I woke later and without the usual feeling. I took some herbs and went back to sleep.
Which is good. I am suspicious of gabapentin and would prefer not to take it. That may not be why my PSA is so high but I am not keen to get prostate cancer quite yet.

Hi Ed.
I found this. I believe it lends evidence to my pet theory that the neural hyperactivity of the sgACC seen in depression is reduced by prazosin via NE alpha-1b receptor blockade.

The subgenual anterior cingulate cortex in mood disorders.

AbstractThe anterior cingulate cortex (ACC) ventral to the genu of the corpus callosum has been implicated in the modulation of emotional behavior on the basis of neuroimaging studies in humans and lesion analyses in experimental animals. In a combined positron emission tomography/magnetic resonance imaging study of mood disorders, we demonstrated that the mean gray matter volume of this "subgenual" ACC (sgACC) cortex is abnormally reduced in subjects with major depressive disorder (MDD) and bipolar disorder, irrespective of mood state. Neuropathological assessments of sgACC tissue acquired postmortem from subjects with MDD or bipolar disorder confirmed the decrement in gray matter volume, and revealed that this abnormality was associated with a reduction in glia, with no equivalent loss of neurons. In positron emission tomography studies, the metabolic activity was elevated in this region in the depressed relative to the remitted phases of the same MDD subjects, and effective antidepressant treatment was associated with a reduction in sgACC activity. Other laboratories replicated and extended these findings, and the clinical importance of this treatment effect was underscored by a study showing that deep brain stimulation of the sgACC ameliorates depressive symptoms in treatment-resistant MDD. This article discusses the functional significance of these findings within the context of the preclinical literature that implicates the putative homologue of this region in the regulation of emotional behavior and stress response. In experimental animals, this region participates in an extended "visceromotor network" of structures that modulates autonomic/neuroendocrine responses and neurotransmitter transmission during the neural processing of reward, fear, and stress. These data thus hold important implications for the development of neural models of depression that can account for the abnormal motivational, neuroendocrine, autonomic, and emotional manifestations evident in human mood disorders.

Now that I can read more that two consecutive sentences at a time, these things are easier for me to understand and process. I even read an entire article in a Scientific American magazine last week. I haven't been able to do this since my remission in 1987, when I read my first and only book cover-to-cover. Ordinarily, I would have to rely on skimming to get through an abstract like this. Even children's books have been beyond me such that I could not read whole paragraphs. When she was a young child, my niece once asked me to read one of her books to her aloud. I couldn't do it. For most of my life, I have not had access to the written word. I think this has been my greatest loss.

I'm confused. You are posting scientific articles as well as your considerations on them all the time. Plus you are using a *very* extensive vocabulary, and not once have I seen you you use words incorrectly.
To me it never seems like you are particularly cognitively "challenged" - quite the opposite, actually.

I didn't say that I couldn't write.
For every paragraph that I struggle to read, I can easily write ten. My problem is not with getting the information out. It is with getting the information in.
I hope that helps to illuminate things.
I am not unintelligent. Neither am I a liar. Either way, I feel insulted for the posture assumed by Europerep. I felt that he challenged the veracity of my self-description rather than respectfully requesting more information from me.

Her never having seen me sans-depression would be a factor, but maybe there's something similar going on.

Yes. The ability to speak well using big words despite depression is a blessing and a curse. Few people even realize that it takes practice and effort to accomplish this. At first, the doctors at the NIH were concerned that I might not be depressed enough to enter their research program. However, after observing me for a few weeks, they understood the dissonance between how I spoke and how I felt. At the study blind breaking, they revealed to me that I was one of the worst cases they had ever seen. I spent the better part of 9 months sitting in a chair, staring off into space. I didn't have the mental energy to focus my eyes on the TV. Later, a professor at New York University called my condition "horrendous". I cried because I felt vindicated. It was reassuring that someone finally understood the severity of my condition.I have never really described to the Psycho-Babble community in detail how I experience depression. It is only recently that I have done so. I think this has something to do with my feeling better and experiencing an awakening. My thoughts are now clearer and I am perhaps more motivated to write these things. The better I feel, the greater is my understanding of the severity of my suffering. At my present rate of progress, I expect that it will take another year to reach full remission. However, I should be able to go to work before that.
I pray that my emerging from depression doesn't follow the patterns of response seen in "Awakenings". I saw the movie. I did not read the book. I imagine the book was even more wrenching than the movie.

If you will forgive the generalisation, psychiatrists make a practice of not believing their patients.
I imagine they would believe their patients twice as often if they were paid half as much.

Oh jeez... did I say that you don't seem depressed to me? No, and that is not by accident.
But if you want to know the truth then yes, I am not buying this "for most of my adult life I wasn't able to read" thing. To me, there appear to be too many logical flaws in this claim when held against both the content and the form of your posts on this forum.
Your reaction to my post strikes me. You usually don't lose your stoic calm even when insulted. Just my observation.

I'm not usually insulted here. Yet, you do it again.Of what importance to you is my medical condition? Why are you so compelled to comment on it without my solicitation? This isn't the first occasion that you have. You have been wrong both times.
Do you think that I'm a liar such that you "are not buying" my self-descriptions and historical accounts? If you don't think I'm a liar or an exaggerator, how do you account for my explanations? Lack of intelligence? A subconsious need to be the "worst"? What?
What is your best guess as to how long it took for me to compose this post? Did you even take this variable into consideration when you opined on my ability to write?
Like I said, don't sweat it. It is not necessary that you understand me. I do wish you would desist on commenting on my condition and treatment, though. I don't find your writings to be helpful or of a positive nature.
I don't mind if you answer my questions throughout this post. I actually prefer that you do. I really would like to know what you think drives me to presumably exaggerate my descriptions of my medical condition?

Oh, it has happened at least a couple of times during the time I have been here. There was this EricFromNC or something like that guy about a year ago. But that's not even the point actually. If you consider that me voicing my thoughts on here is insulting then you are free to do so. After all, this is the internet, and people are free to talk just as they are free to be offended.
>Why are you so compelled to comment on it without my solicitation?Opening a thread on an internet board is solicitation to me. And I am only continuing to post here in this thread because you react in the way you did.
> If you don't think I'm a liar or an exaggerator, how do you account for my explanations?
Quite frankly, that is secondary to me. In the end, it is you who has to answer those questions for yourself. "Europerep is an idiot and has no idea what I'm talking about" is a possible answer, but it's far from being the only one.
> Did you even take this variable into consideration when you opined on my ability to write?
My comment was rather on your ability to comprehend complex texts of scientific nature. There's just no way (that I can think of) that a man who hasn't been able to read for his adult life is able to talk neuroscience with Ed and Link or develop "pet theories" about which type of depression could respond to what type of treatment.
> Like I said, don't sweat it.
I don't even know that that means.
> I don't find your writings to be helpful or of a positive nature.
Maybe others do? As it turns out, I'm not the only one who thinks what I said in my initial post.
