Join the club , I'm on Risperidone, another Atypical and they really pile on the pounds, I put on three stone in a month, its evened out now, thankfully.

Basically they both change the way you deal with sugar, you body on these drugs struggles to deal with sugary food and drink so just turns it into fat (hence the reason you will be offered a blood test at some point to check blood sugar levels).

The best idea is to cut down on all sugar things you have, as I have cut down on fizzy drinks and it made a massive difference.
