Hey Booknut,
I'm still adjusting to this stupid disease, too.
After my colonoscopy last year, I was coming back around from that IV med the makes-you-forget-everything when my GI came and told me I had a "very mild case of ulcerative colitis" and gave me a prescription for more daily meds than I'd ever taken in my life. My husband was there, but he isn't too great at questioning or advocating. So, I didn't take my UC very seriously, quit the meds after about a month, and went into a pretty good flare early this year. I still don't feel my UC is totally controlled.
You'll probably do a lot of experimenting with diet and I really think it's good to get regular exercise, especially something like yoga because that helps stress levels, too.
But speaking of grumpy, the next time I met with my GI, the first thing I said to him was "It's nice to meet you when I'm conscious." I'm not sure how he took that.
Hang in there.
