Actually many, or most, people are intolerant of alcohol after the removal of the gall bladder. Some feel almost like they are having a gall bladder attack. I don't know if there is any involvement with drugs.
In regards to your response to sonia1124 regarding alcohol and gall bladder. I had my gall bladder removed a month ago. I have felt fantastic ever since. Last night I had one mixed drink with my dinner. About an hour or two later, I was just sitting watching t.v. and I started getting that intense pain on the right side of my obdomen. It was the exact same pain I had when I was suffering from a rotten gall bladder. Do you think this had to do with me drinking alcohol? The doctor never said anything about no more alcohol. Then again I didn't ask. This is just the second drink I've had since the surgery and the first one, which I had a little over a week ago didn't seem to bother me. Regardless if it is caused by the alcohol or not, where is the pain coming from? My gall bladder is gone, so it can't be that.
