The good thing is that I sleep like a zombie, the bad thing is that I gained 30 pounds within a few months. What will happen if I quit taking the seroquel, i.e. seizures, etc? The other meds I take are 30mg morphine, soma 350mg, and Norco 325mg every six hours, as needed for breakthough pain. I have been experiencing back pain since 1998 and finally had surgery (Double fusion) in 2006. I have had severe pain even after shock therapy prior to my back surgery. I experienced grand mal seizures getting off Xanax and am concerned if I have them again. Will I experience side effects by stopping the seroquel cold turkey? I cannot fit into any of my clothes, which does not help my severe depression. The pain medicine is for a double fusion that did not take back in April 2006. Plus, I have anxiety attacks if I go anywhere other than the doctors. Any help on the weight loss and quitting the seroquel?
