Does anyone here experience cramping, gas, and lower stomach pain especially while riding in a car or on a plane. I feel like my insides are very sensitive to the small amount of vibration from the road and possibly by the pressurization of an airplane cabin. I am petrified to get in a car or on a plane any more. A plane is the worst because there are times when you're trapped and aren't allowed out of your seat to relieve yourself. I am actually concerned that I am going to have to quit my job because of this embarrasing problem (I have to be on a plane and in a car a lot to get to meetings). Any thoughts on how to control this would be appreciated!
