I took Seroquel for 3 months in 50mg for sleep, didn't help but had no wieght gain.
now about Zyprexa, when i first started it i was already overweight, but it made me put on around 10lbs then i got stuck on my current wight, I noticed if I stay away from carbs and exercise i start to lose something like 2/3albs a week. but to be honest im too tired from my meds to workout regularly.
