My IBS is greatly triggered by exercise. Specifically runnning. Just ran a race this morning and I'm in agony now. Before the race I took 2 Excedrin (which has caffeine) to replace my morning coffee.

The combination of the aspirin and the exercise seems to be a wicked trigger for IBS. *sigh* Lemme know your thoughts.
