I have been on Quetiapine for a year now and had no weight gain, I think it’s different for everyone I started on 25 mg and am now on 50 mg a day. You should be okay, if ur worried about weight gain start on a lower dosage and keep exercising!! X

I have been on serequel for about 3 yrs now and i was up on 300mg now im only taking 100mg and i have gained about 80 pounds so if i were u I wouldn’t take it i hoped i never took it either but it helps me fall asleep faster then other medication has so thats y i keep taking it and also the withdrawal from serequel is the worst thing that has ever happened to me i have never had withdrawals till i started taking this medication when i was on 300 mg i asked my doctor if she can take me off it cause I gained a lot of weight with it so she took me off completely and i had the worst withdrawal ever so i told her to put me on again but now im only in 100 mg a night

I've been taking it for 6 years. I'm on 2x 50mg xr during the day and 100mg at night. I started when I was 28 nd very active and now I'm 34 and less active. I've gained about 10kg over that whole time frame which I blame partially on the meds and partially on lifestyle changes and metabolic changes. I do think I crave carbs and sugar more due to it especially at night after I've taken the fast acting one. If I don't go to bed and sleep when it kicks in I will stay up and often end up binge eating. Overall I am willing to take the weight gain and enjoy my life more. It gave me the ability to finish college, work full time and maintain a relationship.

I actually have experience with this as I too have anorexia and my psych put me on quetipine for sleep and it has helped greatly and I haven't experienced side effects of weight gain
