Don't go on Risperdal. I knew this person who went from an underweight BMI to an obese BMI in 33 days. I've also heard of other stories of people gaining like 50 pounds in a couple months.

I'm sure thats not the case for everyone though and this women just had a weird reaction to it.

I'm on Prestiq. It works great and I've had no issues. But people do often become manic after awhile on it and its hard to come off of. I have not had that problem though.
