I just got the sleeve 3weeks ago my highest weight was 441 when I had my surgery weighed in at 421 after 2 weeks post op I was 390. I have to admit its a little harder than I expected it to be the hardest thing for me is that I'm a big drinker of water and only being able to take sips drives me nuts I don't get hungry but sometimes I wanna eat what I see other people around me eating but I do have control I just feel at times I'm really tired and don't feel like myself anymore .
