oh Pat86,
I feel you , i had the same problem with seroquel and now i have metabolic syndrome/ insulin intolerance and it has caused significant weight gain to the point of diabetes. My endocrinologist is sure the Seroquel caused it, today i see my pdoc and am asking again to have the seroquel changed to saphris.
I am at my wits end just like you , good luck with your weight and know you are not alone.
warmest regards, Tams
