I had a band to sleeve revision almost 6 months ago. As for pain post op, I was in less pain, though the band was my first ever surgery. I took pain meds for three days then. For the sleeve I didn't take anything after the first night. Although I did stay in the hospital 2 days due to nausea. And I did have some nausea weeks 2-4. As for restriction. It is so much different than with the band. A few bites with the band and I'd be in pain, but then I could eat anything. I never found my sweet spot. With the sleeve, no pain from being stuck, just an uncomfortable feeling if I ate to much. I'm much happier with the sleeve I'm a slow loser, not terribly, but slower than a lot of people on here. Like I said I'm almost 6 months out and including my pre op im just under 50lbs lost. Would I go back to the band, hell no, or would I ever recommend it to anyone, no way. The band is horrible and I don't know why it's still used. Do I regret having the sleeve, not a bit, only that I didn't revise sooner, maybe I would not have gained back everything I lost with the band [emoji20].
