I'm trying to figure out if what I have is IBS as I've been to several doctors and they can't seem to find anything wrong. For the last 2 years, within 20 minutes of waking up every morning I suddenly get severe abdominal cramps and an urgency to go to the bathroom and I have diarrhea. This only happens once I get up regardless of what time it is. I have never woken up with these symptoms, I only get the cramps and urgency after I've been up for a short time. I sometimes then have to go to the bathroom an additional 1 or 2 times within the next couple of hours. After this time my stomach usually calms down and I am fine for the rest of the day although on occassion it lasts most of the day. The only thing that controls the diarrhea and gives me relatively normal stools is Imodium. I have to take 2 before bedtime and 2 in the morning. If I stop it for a few days the diarrhea returns. I've also tried hyoscyamine and lomotil but neither has helped me. I've had 2 colonoscopies, an endoscopy, a small bowel xray and a small bowel capsule study done and they have all come back normal. In addition, I've had stools samples tested and blood work done and nothing wrong has shown up on any of these test. I'm kind of at my wits ends as to figure out what's wrong and what to do next to eliminate my symptoms since every test has come back normal. Having this problem every morning has affected my commute to work as I find the need to stop many times on the way to work to find a bathroom. The last doctor said that it's probably IBS, but didn't really tell me how to solve my problems in the morning.
