I was one of the rare cases that happened. I was on Zoloft and on day 10 i crashed. When i say crashed, i mean bad. I had severe hallucinations thinking people were after me and stuff. Zoloft gave me way too much energy and i couldn't sleep which is why i think i crashed. Don't get me wrong, the medicine did make me happy like its intended to. Too happy in fact- it was like a eurphoria of happyness. Oh and during the 10 days i was on it, i got crazy ripped. I only worked out twice but they were about 3 hour workouts each. I almost had abs after this. After the workout i wouldn't even be tired. I am 17 and am not very athletic. Like i said, don't be scared off by the medicine, what happened to me was rare. I was in the hospital twice.
