schizophrenia
"When I was 14 I was put on 450mg/day before bed time and within 6 months I gained 25-30 pounds. It worked super well to get rid of my hallucinations (including the tactile ones) but it made me extremely zombie-like. My grades slipped at school, and I slept as soon as I got home till the next morning. The first day I slept 22 hours. This medicine made me so hungry all the time and no matter how much I ate I was never full."
