Zyprexa made me gain massive weight like over 20 lbs in around 2 months I'd advise that you lower your calories straight away to try and limit the weight gain I believe some people refer to it as metabolic death. I'll never use any AP ever again I was also sleeping 12 hours a day and felt tired and groggy when I was awake. But I suppose if it helps then that's good as long as you're ok with gain some chubb, which I wasn't.
