I was 30 lbs overweight when I got put on meds that caused a 70 lb weight gain. risperidal. I wasn't eating anything and still gained weight. now I'm 100 lbs overweight and can generally lose about 30 to 40 lbs with major effort. I looked into weight loss surgery I hate being fat. but honestly I hate crazy more. I'm not sure if I'll ever get this weight off. it's a huge challenge.
