Weird (and probably TMI) suggestion. If you're having IBS cramps and the heat isn't helping; try a vibrator on a low setting. Either get someone else to gently move it around the abdomen, or lie on your stomach on top of it. I use a mains powered 'magic wand' style one for this, and it helps a lot. Another idea is a TENS unit; dual channel if possible. Stick the pads in a square on your belly, and it helps the pain. Thought I would share: IBS spoonies unite! *hugs*
