I think we all get tired of having to deal with these issues. I’ve noticed that I also get tired of the consequences of not dealing with the issues, so that’s the real choice, of course. Some people swear by a low FODMAP diet, but it really is a big change. One much smaller step to consider would be to try it for a little while, just to have better information about the real life trade-offs (how much relief vs. how much nuisance). Another possibility would be to try one of the biologic medications, which would be much simpler than a big dietary change.
Since you’re not married to this new GI you have the option of finding a different one whose treatment philosophy is more comfortable for you. I hope you feel better soon!
