I'm 6 months post op and I didn't vomit right off, it took me 5 months to experience it. It was my fault and not my doctor or the band bc I either ate right after drinking or vice versus. At 4.5 filled, I was still able to eat Krispy Kreme doughnuts and 6" subs from subway & I gained 12lbs bk.:-( Now I just got another fill and I'm feeling more restricted and I love it bc I'm eager to lose weight and make better decisions about what I enter into my body. My starting weight was 325lbs I got down to 275 & now I'm 284 & I'm DETERMINDED to lose more & keep it off. Good luck & blessings to us all (banders) to stay strong and defeat the fat monster.
