Atomoxetine
"My Doctor put me on basically the fastest titration. 40mg for 4 days then 80mg after that. The first 4 days on 40mg were awful. The worst of the side effects being insomnia. I had to call out of the work for the a few days to catch up on sleep. I could not fall asleep at ALL. The Doc prescribed Trazadone to sleep. That helped after being sleeped deprived for a few days. I've heard of people upping their dose and having the side effects lessen and positive side effects increased. WRONG. First day on 80mg I had crippling nausea, body aches, massive headache, off the chart irritability, burning urination (with white discharge), and thoughts of SUICIDE. No joke. I've read of people having this happen them but it's a rare side effect."
