Even though I'm about 2 and a half years post op, I've been up and down the past year or so. But not the kind of up and down (mostly up) that I was before the sleeve. By up and down now I mean maybe 12-15 pounds, which seems to be related more to my workouts and muscle gain or loss for the most part. Not the 20-40 pounds like before the sleeve. I'm still very happy I went through getting the sleeve over 2 and a half years ago.....hope I can still say that 10-20 years from now. The first one I was almost at my heaviest....320-ish. The second one I was about around my lowest (low 220's I think) and the last one was a week ago in the mid 230's.
