I can totally relate, malau! :imbar I also struggled with diarrhea during nursing school, mainly on clinical days, but also in my first few years of working as a nurse. (And it's still my body's typical reaction to stress-- Not to the point of irritable bowel or colitis, however-- thankfully!) During my first job in Med/Surg working night shift, I even had my favorite bathroom near the back entrance of the hospital. :imbar I generally only had problems BEFORE clinicals/my shift began, not during. (I'm a terrible "what if-er".) I also had no problems if I was nowhere near the hospital on days off.
Chewable Pepto Bismol tablets were my friend as well as a *LOT* of prayer and reading Bible verses addressing fear which I had written on 3x5 cards in my car. (I can remember someone honking at me at a stoplight after it'd turned green because I was fervently reading my Bible verses and popping Peptos!
) I imagine that increasing your fiber with Metamucil or Citrucel may help bulk things up for you, but Immodium or Pepto Bismol can help in emergencies. If it keeps up though, it might be good to see your doctor as fedupnurse mentioned.
Oh how I wish allnurses b.b. had been there for me in years past...
