insomnia
"I have been taking it for four nights. I fall asleep for about an hour and go into a state of mind in which my mind is awake but my body is asleep. Then my body wakes up after one hour and I am awake for the rest of the night feeling extremely fidgety like I need to pace or jump out of my skin. The feeling continues for about 12 hours. I can't take it anymore.  If it had no effect, I would keep taking it waiting for that magical night that many seem to express happens.  This reaction frightens me. I don't want to chance rage like Wellbutrin causes in me."
