Hi Larry

I have a couple more questions.

1) Is it essential that you take DL-Phe or L-Tyr with absolutely no other substances? You see, I also take Diazepam in the morning and I'm wondering if it would be OK to take the DL-Phe or L-Tyr together with the Diazepam. Or will these substances interact with eachother or otherwise compete for similar enzymes and chemical pathways in my system thereby reducing the efficacy of one or the other (or both) of these substances in my body?

2) I know that to get the same dopamine effect that ideally I should approximately double the dose of DL-Phe over the amount of L-Tyr that I currently take each morning. However, I have had a look in my local health food store and a bottle of 500mg DL-Phe tablets is actually more expensive than a bottle of 500mg L-Tyr tablets. Therefore, taking cost considerations into account, my question therefore is would you consider that a 500mg dose of DL-Phe would be more beneficial than a 500mg dose of L-Tyr notwitstanding that less dopamine will be produced in my body, BUT because this lower dopamine production is offset by an approximately equal amount of PEA production in my body from the d-isomer in the DL-Phe? In other words will I get a better result from a higher outright dopamine concentration in my body OR will a better result be achieved with a lower concentration of dopamine acting in concert together with an approximately equal concentration of PEA in my system?

As an analogy (I LOVE my analogies) I generally don't like listening to a either a violin or a cello in isolation (a screeching violin on it's own can be extremely irritating in fact) but the two instruments playing together in concert can produce some rather soothing sounds!!!

Thanks Larry
