[QUOTE=GoodEnough]Go to any pharmacy and buy 10 500 mg. tables of generic Ciproflaxin. At the first onset of diarreaha, start to take it and take two per day for five days. It will disappear within hours after taking the first pill. This is a seriously excellent antibiotic and it works wonders.[/QUOTE]I've had the same problem both times I've visited the PI. Not sure what causes it either since I am careful to only drink bottled water and pretty careful about what I eat. However, when the problem arose a week or so ago during my visit, I looked on the Internet and found information recommending taking an antibiotic and immodium. I bought some immodium and Ciproflaxin (antibiotic). The Ciproflaxin worked great - within a day, no more problem. From now on when I visit, I'll keep some on hand just in case.
