Hate to say it but...this, too, will pass. You sound very brave eating salads, etc. for me, butt burn issues are very related to what I have eaten. For months after takedown I ate the same boring, bland diet but it paid off with almost no butt burn. Then, id systematically introduce one new food at a time. If I experienced no butt burn this food became a regular part of my diet. If butt burn resulted, I waited several weeks before introducing the food again. One surprise was that my butt loved McDonald's French fries! Go figure! Best wishes. Keep a food diary and record results. I didn't use Imodium, etc. Just foods which would work for me. It was all trial and error.
