After almost 11 years, I've been able to classify my IBS/Life into categories. I have good days, not so good days, bad days, and really really bad days. When I have bad or really really bad attack, I get very tired afterwards. The worse the attack, the more tired I get. And I always have to pee 15-20 minutes later, for some reason. Does anyone else get tired? Do you feel like you need a nap after a lengthy bathroom episode?
