I am on 400 mg a day.
The first two weeks I gained almost 8 pounds.
After that I changed my diet, more protein and less carbs. I also work out three times a week and walk everyday. I have lost almost 12 pounds and feel really healthy.

My anxious state of being has become really calm, and I actually feel I have more emotions now- but in a more normal manner.

I am amazed of how well the Seroquel is working, and I hope it stays that way.
Did have some side-effects the first couple of weeks, but those are gone now.

Hope it works out well for you
