> Thats a good question since it can be hard to tell. Dopamine should increase positive mood and can cause eurphoria. Too much would increase paranoia. It also increase your ability to focus on one thing. The biggest difference is that it can make you obsessive about one thing and it increases your desire for pleasurable experiences such as sex and drugs. It increases libido.

> Norepinephrine seems to raise blood pressure and can cause tinnitus as well as induce seizures. Norepinephrine decrease libido in males because Norepinephrine is released after orgasm and causes the penis to go flaccid. So just imagine having that chemical elevated all the time. Norepinephrine promotes wakefulness and energy as well.
>This sounds like a vast oversimplification, because a specific norepinephrine reuptake inhibitor, Strattera, is known to cause sedation in a lot of people.
Stimulation seems to come, somewhat mysteriously, from a mixture of dopamine and norepinephrine. Increasing dopamine, for instance, tends to produce in people and lab animals semi-involuntary movements, making it very hard to remain still. Dopamine seems to be an essential part of stimulation.
