recently when I have a half a glass of wine or when I eat a burgar I get very ill. I had gastric bypass 18yrs ago lost 150lbs. that I have managed to keep off with the up and down of 10lbs. Im so concerned as ive also had lower abdominal pain off and on that ive never experienced either. Ive had my gallbladder out over 20yrs ago, and other than these things feel wonderful in my life. Should I worry that I can no longer ingest meats or even the smallest amount of alcohol? im perfectlty fine not to ever drink again its just noticeable.
