I did FODMAP diet last fall when horrible abdominal pain occurred. My PA recommended it. The diet worked for me. If I remember correctly you restrict yourself from 3 to 4 weeks, something relatively short-term. Then you slowly add in one non Fodmap food at a time to see what your digestive tract can handle. I didn't think the restrictions that big a deal, especially for such a short term. I suspected I had SIBO but no one would refer me for a test. I read the Johns Hopkins write up on the FODMAP diet which said it could help with SIBO and IBS. Depending on what is causing your problems, it may work for you. If I were you I'd try it and see what happens. Print out the Fodmap list of food to eat/don't eat and go shopping. If it doesn't work for you, that adds one more piece of information for you. If it does work, life changing. Here is a link to a list of foods acceptable in a FODMAP diet; there should be somewhere on the internet a printable chart. You can spend the time finding it. Good luck! https://dietingwell.com/low-fodmap-foods-list/
