My weight gain is mainly due to olanzapine. I also took olanzapine. Later, I switched to aripiprazole and didn't gain weight. I lost a little weight. After leaving the hospital, I tried to diet and finally lost weight. But do you think that's enough? No, I lost my limbs, my face hasn't changed much, and my stomach is still strong. Because of olanzapine, I, a bitch who has blocked all kinds of peach blossoms, have not found my peers interested in me for more than three years!
