My Dr. has perscribed 40 mg of strattera twice a day. When I do this I become a zombie. I just want to sit and do nothing. So, I only that the one 40 mg. pill in the morning. But then my brain works all night. Last night I played or tried to play a game in my sleep all night. I guess I'm asleep, but my brains keeps working. I heard about melatonin and wondered if it would help me and how much I should take.
