Seroquel and water weight

At first I didn't gain weight from Seroquel. but after 3 years on it all of a sudden I am retaining fluid and gained 15 lbs in 2 months all water. I have stopped cold turkey on Seroquel and of course I am not sleeping well and it doesn't help that I am up about 7 times a night peeing because of all the water weight that is coming out. I think Seroquel is more addictive than Xanax or other drugs - the sleeping part was very good but who wants to keep retaining water and go from a size 12 to a 16 and it isn't stopping so I figured I would try stopping the Seroquel to see what happens = so far I think the weight is coming off (only 2 days off Seroquel) Doctors don't care about the weight gain. I wish I never went on it.
