On a tour last year through Europe, I had at times , quite severe diaharrea. Luckily, I was given some anti diaharrea tablets, but the whole experience caused some very anxious moments ,as on a bus it is not always easy to stop ( was a toilet on board,for emergencies only, and any smells easily spread thru the bus).I didn't really relax and enjoy the scenery, and decided this would be my last tour . The travel bug has hit again, how do other travellers cope with this basic problem?
