Geodon has been a mixed blessing for me. It doesn't make me gain weight---in fact, I lost weight when I first went on it---or mess with my blood sugars. Unfortunately, it also doesn't work as well to keep mania at bay, which is why I'm on Zyprexa again. I take Geodon before bedtime with a big spoonful of peanut butter, which provides the fat needed to absorb it without a ginormous amount of calories.
