I was prescribed 50mg Seroquel for sleep and took it every night for a few months. It worked well and had no side effects. The following year I was prescribed 300mg nightly for mood stabilization and often I would get an urge to eat a lot of food after taking it. I didn't gain a significant amount of weight but I would binge a few times a week at night. There were other side effects that ultimately led to me changing medication.
