Hey JennyGirl -
Yes, do check out the PCOS forum under "Dieting with Obstacles". We also have a Weight Loss Surgery forum, which might address some of the more specific challenges you face post-GB. We have groups by age range, by eating plan including South Beach, etc. Look around and explore. You're sure to find a spot or several that feel perfect in no time.
Stick around...I can't wait to get to know you better!
