Has anyone had experience with this? 

I was prescribed quetiapine about a month ago while I was an inpatient on a psych ward and I'm seriously considering speaking to my psychiatrist about stopping.

I could deal with the grogginess, sleepiness, feeling meh but I don't think I can cope with the weight gain. Before I got real bad in May I was going to the gym and eating clean despite everything and I'm not sure how much weight I lost but it was noticeable (after a year of letting myself go). I'd say easily 30-50lb. In the last month or so I've gained 10.

I'm not eating more than I was, if anything less as I haven't been drinking alcohol like I used to.  Recently I can go one or two days and if someone didn't remind me I'd literally forget to eat. 

I'm just worried because 100% have body image issues and this weight gain is making me depressed and unmotivated and I feel like that will make me decline, even with extra meds.

Has anyone had experience, any tips to prevent or limit weight gain? Or any alternative mood stabilisers they were prescribed after trying quetiapine and it not working out for them?
