I agree about taking imodium preventively and regularly per directions when away from home.I also agree about wearing an adult panty-diaper just for the trip. Ever since I had a huge mess suddenly happen before the car could be pulled over, I wear one even if traveling only an hour. I was surprised by how it feels fine and nobody can tell. It's in place of underwear so there's no bulk.I have a card saying "I Can't Wait", that I have a medical condition that makes it necessary for me to use a restroom quickly; that gets me into employee restrooms in places that don't provide one for the public. I rarely need it but I can get at it fast in my purse.I am very grateful to my husband's sensitivity that led him to buy me a portable, flushable toilet that we keep handy in the back of my minivan, with tp and hand sanitizer. The windows are tinted, the toilet is placed so it looks like I'm on a seat, and the blanket that covers it becomes a shawl to hide my whole backside just in case someone comes and puts his hands up to the window to peer inside, which of course never happens. Whatever that chemical is in it, it works so well, there is absolutely no odor or bad smell after flushing, providing you don't have a mess on you (because you have a diaper-panty on and can dispose that out of your car into a gas station or other trashbin). Although I rarely use it, maybe only 2-5 times/year, I'm so comforted knowing that it's in the car, that allowing space for it is a requirement when considering the car to replace my old and failing 14year old car. So, be creative and eat carefully if that triggers problems for you, drink calming tea and by all means.... GO and have fun!Cathy
