Curious how much you've changed your diet, etc.? Any triggers that have caused you problems in the past; stress, drinking too much, a big cheese steak?
For the first six months after my diagnosis, I kept a diary of everything I ate and drank and recorded any pain it caused and how it impacted my bowel movements. This revealed that nuts, corn, and some of the microbrews, particularly in draft form and in particular wheat beers, caused problems. I was pretty diligent about it with times, quantity etc. It also revealed that some rye alcohol also caused problems, but not as serious.
Knowing all of this, I eliminated these from my diet, and pick and choose my moments when I break the rules, knowing full well the consequences. Only in the last two years have I really started to drink draft microbrews again and haven't had the same reactions as I used to.
The only other things I'm still working on is travel. No idea why but flying, in particular with time changes, seems to cause a reaction, usually after about 48 hours in. It's been bizarre and always happens at the worst times, but it's 3-4 hours midday of "crohns fatigue" nearly every trip. Still can't figure it out, especially as I used to work internationally and had no troubles travelling.
