Hi - I'm 2 1/2 years out and am starting to regain a little, which is why I am here. The things I have found worked the best so far are:
1) Go back to basics. 3 meals, no snacks, protein first, don't drink 30 mins pre and post meals. Even go back to your pre-surgery liquid diet for a couple of weeks (if you did one). If necessary, re-read the info from your surgeon to remind you!
2) This site/app has been really good at showing me that I was eating too much (snacking). I am aiming for 900 calories a day and I have stopped gaining and am slowly heading back down.
3) Get rid of any food you can eat easily, as it probably means you'll overeat it. I have ditched all crackers and peanut putter and only get cheese every second week, as these became my default foods.

Hope that helps.

i believe its soo hard even without surgery to get back on the track for weight loss....but i agree with the others...be sure to remember what it was like before surgery and the whole process leading up to it...watch your eating, no drinking before or after 30 mins of a meal..PROTEIN PROTEIN...and make your meals last...im sure all will be well...you made it 120 lbs down..37 isnt much but i know you can do it

A tight sleeve is good! It will loosen a bit over time. I think my sleeve kept me under (or near) 6-700 calories most of my first year, -even a bit beyond that.
