That's right, I have this weird anxiety where when I'm on the road (bus, car etc) I get a pain in my stomach and then I want to use the toilet badly. That's probably because I have crohn's disease but I'm in remission and it's only stress that causes these symptoms, 3 years ago I had an "accident" and ever since I don't like being in places with no toilets around.

Anyways, in a week or so I'm travelling outside the country and there will be a lot of car rides up to 3 hours each and I don't know how to calm myself down. Any tips that can help me please?
