I was wondering what medication did you find to substitute for the seroquel?  I was trying to get off of seroquel and got down to 25mgs.  I was trying lamictal.  Unfortunately, I was having some very unpleasant side effects on the lamictal and had to discontinue it.   I did go off of seroquel and was substituting geodan but I could not get to sleep at all for 6 days.  I did lose about 7lbs. overnight not on seroquel and I know that sounds impossible but my scale read 7lbs.less.    I think the reason you are gaining a few pounds is because you had developed an eating habit with seroquel and it will take a while to retrain your brain to not have the cravings that seroquel gave you.   Let me know how you are doing in the next week please.  I am really interested in hearing of someone stopping seroquel after 3 years and staying off of it.  Good Luck!
