I have suffered with IBS most of my life. Always worrying about access to bathrooms. I can go long periods of time with no problems but anxiety will trigger an immediate need to get to a bathroom. Dr. has prescribed dicyclomine. Anyone use this just when you are going to be in an anxious situation ie taking my husband to the ER? Going on an airplane? Dining out with friends? Etc? Maybe taking it before the event? Or should it be once a day?Any suggestions are welcome.
