I've been taking;
Seroquel (100mg at night)
Respiridone (1mg at morning & night)
Lithium 1200mg (600 morning & night)
Seroquel and Respiridone both cause weight gain as a side effect. They have definitely helped me though. I gained a lot of weight since taking them, without any changes to my daily routine (probably about 50lbs at the worst point). There is a drug that I am going to ask my Dr. about, Metformin. It is a drug to control blood sugar and weight gain caused by psych. meds.
If Metformin is not an option for me, I am going to ask my Dr. for a change in meds.
