Care to share other tips?
Gordon makes some good ones. I'll also add...
Pound the yogurt (with live cultures) 2-3 times a day the week before your trip and eat it daily while there. If yogurt isn't your thing, you can take acidophilus tablets that accomplish the same thing... loading your digestive tract up with good bacteria that will attack harmful bacteria that you may ingest.
Take Pepto Bismol as prescribed a couple of days before and daily during your stay.
Fruits and Vegetables: If you can't peel it or cook it, don't eat it.
Start the trip with a fresh, new tooth brush. I'd use the one from a previous trip and came to the conclusion that any trace amount of bacteria from the previous trip would grow and be a real problem. But that's only a SWAG.
The only water that goes into your mouth come directly out of a sealed bottle of agua purificada. Showering especially. I know it sounds gross, but I apparently had a habit of sucking the water out of my mustache while showering subconsciously. I discovered myself doing it while in Mexico of all places. I now bite my lips to avoid it and it's less filling too!
I used to stay away from ice but I think I cured the problem with the above.
Contrary to comments above about excessive drinking, I've found a couple shots of tequila a day helps kill any harmful bacteria.
Money is filthy. Always wash your hands after handling it. As a matter of fact, you simply cannot wash your hands enough while abroad.
Save eating rare steaks and medium rare hamburgers for at home. Order meats well done.
Error on the side of caution and don't experiment eating stuff you're not sure about.
