I have an old 4 mm band, and am researching removal and revision to the sleeve. I was banded 5/2005 - I lost 60 pounds relatively easily, bit then started infertility treatments and after two miscarriages and two,successful pregnancies, I am right back where I started. I can't eat foods that are good for me, and I can too easily cheat the band....hoping the sleeve will give me a new shot to get this weight off once and for all!
