As you know, it can be very tough to stop gaining and to begin to lose.
I hear varying opinions on low -dose Seroquel. Some docs say the low dose does nothing to hold onto weight. Others say that even those with a low does tend to gain weight!

I did have a time when I was loosing weight when taking a higher doses of Seroquel. I was doing a ketogenic diet at the time. I was not doing a fad type of keto, I was doing the old one, the one set up to help kids with seizures. (This version worked well, yet gave me very high cholesterol/lipids.

Sounds like you are trying and you can only do whatever you can do!
Keep it up! Much Love
