"I was put on Celexa, Depakote, and Seroquel when I was a month into being 13 years old. I was fine for a week then the voices returned with a vengeance, much worse and far more taunting and tormenting than ever before (or since).  I became a zombie, unable to communicate the problems to my doctor or family. In addition, when I described problems to my doctor he insisted Seroquel didn't cause those effects. Drowsiness, craving sugar, problems with walking and balance, and becoming a far more ill person than I was when I began the medication. I gained 60 lbs in three months. When I stopped Seroquel, I returned to "base sanity". My weight returned to normal."
