adhd
"Hi, 36 year old male here.  I've been on Strattera for 2 weeks already and so far so good.  My metabolism has always been fast so I noticed an improvement on the 1st day!  I was able to concentrate and focus at work and it has enabled me to focus in class(I'm in grad school).  For me, the medicine kicks in about 1/2 hour after I take it and for the first 10-15 minutes or so, I get a sort of sleepy feeling but once I start a mental activity, it goes away.  Its very weird because I tried to take it at night and although it gives me that "sleepy" feeling, the medicine keeps my brain awake.  One time I took it at 9pm and I couldn't fall asleep till 4am!  After that event, I just find it better to take it in the morning after my workout."
