Hi there!
I am VERY disapointed with my so called progress!!! I am a year out and have only lost 80lbs (most of which I have lost before surgery.) I too can eat larger portions than I think I should be able to eat. I was exercising and dieting religiously and would only lose 1 pound every 7-14 days!! Needless to say I gave up! Now, I haven't gained any weight back no matter what I do or don't do, but it's still frustrated!
I should mention that when I had my sleeve done, I also had a nissen fundoplication (a proceedure that helps control severe acid reflux) and I was told that I would never be able to gulp liquids, burp, or vomit...EVER! Guess what? I can do those things (have been doing them frequently) I went to see a different surgeon (my actual surgeon refused to scope me because he thought I was being a lazy cry baby) and she says that my surgeon wasn't supposed to do both proceedures especially not at once and that my stomach is way bigger than it should be for someone who has had a sleeve.....
Get a second opinion!
