How long before the weight gain created by Seroquel is reversed after discontinuation?

I gained 40 pds in three months on seroquel. With me the weight loss began immediatly as well as my hunger pains subsiding. I have been off of it for 2 months and have lost 30 pds. I have been taking seroquel for 5 years. Initially I gained 50 pounds, but after starting a healthy eating programme and gentle excercise the pounds are starting to come off.
