4 years ago I had a Colonoscopy and Endoscopy. I also had a SIBO test and was tested positive for SIBO. Well I recently switched doctors and he said my SIBO was highly unlikely unless I had major surgery at some point. He didn't want to run any tests on me and put me on Nortriptyline. Does that sound like a load of croc to you guys? I have been reading about the horrible side effects of this medicine and am thinking about getting a second opinion. What do you guys think? The problem is extreme gas and not just the feeling of it, but releasing it all night long constantly.
