I take 150 MG of Zoloft at 6:00 p.m. I was having trouble sleeping so my psychiatrist suggested Seroquel XR I am on 300 mg and take it at 8:00 p.m. It does put me to sleep but I have gained so much weight…so I was wondering if there is another type of drug out there that will do the same thing as the Seroquel XR without the weight gain.
