I also take Seroquel and had the same issues .

I started taking Metformin ER and it has kept my weight the same and prevented any new weight gain. My blood work is all in the normal range as well. Metformin decreases your urges for carbs. So you are not as hungry. it helps prevent any new weight gain.

Seroquel can cause metabolic syndrome and also diabetes. The metformin will help prevent those things along with diet and exercise. It will help your glucose levels and lipid profile.

I am still over weight now by about 40 lbs. But all my blood work is in a good healthy range even though my BMI is obese technically. But I am healthy.

So I would say Metformin helps a lot.

Ask your doctor for Metformin ER because it will have less side effects (food will go right through you)

And be sure to take it right after a meal. Your doctor should probably prescribe 500mg ER twice a day. Once in the morning and once at night.
