This made me feel like I smoked an ounce of weed. I had gained to much weight so the Dr. took me off the med and now I am on Remeron.

Seroquel leaves one feeling very tired and sleepy. It is also known to cause significant weight gain. One user reported that within three months, regardless of exercising daily and not changing eating habits, over 50 pounds were gain. In addition to a very sedated feeling with little to no interest in daily activities, weight gain is a side effect that should not be ignored. Users have reported feeling like a zombie and very sleepy.
