A few suggestions for you:1. Go to the Blog section of this site and look way back for my Blog: IBD/IBS Author. I wrote a post about traveling with IBD or IBS. 2. Join the Crohn's and Colitis Foundation of America www.ccfa.org and with your membership you get a card that says something like: "I Can't Wait. The holder of this card has a bowel disease that causes them to have to use the bathroom urgently." You could also write out your own card saying something like this. I've used mine a few times to jump a bathroom line. 3. I would also suggest that you book an aisle seat a few rows from a bathroom.4. Also, talk to one of the flight attendants in your cabin and tell them you have a Bowel disease that can mean you urgently have to use the bathroom. And if there's a line could they help you get into the next bathroom. Flight attendants will help you because they don't want you to have a problem because then it becomes their problem.The relaxation techniques are good. Also, take you iPod, books, magazines, etc. to keep yourself occupied and your mind off your gut. You can do it, just go prepared. I travel all over the U.S. and internationally and I have both IBD and IBS. You are smart and right not to take Imodium if you don't have actual D, it can cause problems taking it without actual D. Good luck, you can do it!Elizabeth
