I have been on Abilify for a few months and have gained almost twenty pounds. It's so depressing. I've tried dieting. I've even had the flu and ate only applesauce for a whole week and still lost nothing. It seems that Abilify makes it impossible to lose weight. I"m going to ask my doctor if I can decrease my Abilify (currently at 20mg) and increase my lamictal (currently at 100mg). I'm so afraid that I'm just going to keep on gaining weight until I become a total whale. I gained 30lbs on Seroquel and can't go through that again.
