"this drug was prescribed to me for depression and anxiety, but it had an unexpected effect. i simply cannot stop eating. i eat the entire day, and right after i finish eating a full meal, i feel hungry as if i hadn&#039;t eaten anything, so i eat again and again. i have gained 9 kg in less than 3 weeks and i am loving it. people always make fun of me because i&#039;m skinny, i never thought a psychiatric drug could fix this.. i am so happy when i look in the mirror. olanzapine is the best drug if you are a skinny ectomorph who struggles with lack of appetite."
