I have an actaul fear of vomiting too and it almost held me from getting the band also. I just told myself I would be very careful and follow every rule. I have NEVER slimed, PBed or vomited EVER. Never even a nausea feeling. I take small bites, chew very well and put my fork down between bites to try to feel the full feeling before it's too late. It has all worked for me. Good luck in your decision, but don't let it hold you back because I think you can control it if you try.
