OP, one other thought I neglected in my novella length post was IF. Intermittent fasting, originally brought to my attention by Mike O'donnell, has been a huge help to me. Looking back, the writing should have been on the wall. Regardless of their intent, doctors take me off food as soon as I'm admitted to the hospital. Now, if I feel like I'm having a flareup, I begin a 12 hour waking fast. In other words, the clock is only running while I'm awake.
Sometimes, your guts just need a break.
