hello. i haven't had any severe g.i. conditions although when i was still drinking, i did have some rather painful symptoms that may have been precursors to serious issues. drinking and smoking can do a lot of damage to the body, and your md should have addressed these. unfortunately, the burden of obtaining current and clinically tested info is being placed on the consumer more these days. keep doing your own research in addition to any therapies you may be trying, and if you decide to stop the booze, there are people here that will help and shoot you straight. good luck--gm
I really don't know the answers to your questions, but i would advise going back to the gastro doctor and asking him. In the meantime try to limit these things that irritate the problem. Good wishes to you. TJ
