Hi there - me too. I lost 25+ lbs. before my GB was removed, and after surgery gained that and then some! Of course, I'm now over 40 so weight loss is almost impossible without extreme dieting and hours of exercising. I'm not able to do both, but I do try to watch my intake and exercise moderately on daily basis.
That's about the only advice I can offer - I haven't really lost any of the weight, but then I haven't gained more either.
Good luck to you both,
