hey all I was banded on 8-4-2011 . I have had many fills but can't seem to get to my sweet spot. I started out at 262 and right now am 193. every time I get a fill my band gets way to tight and I cant keep food down because my band. im only at 3.5 cc and cant seem to get anymore fills . I stayed the same weight for almost 4 months now. what can I do to get back on track ?
