We will be at the Sabor islander 9-26 to 10-3. last tine in Cozumel I got sick ( food water?) Only got to dive 2 times. Any sugestions how to prevent this?
Here is my belief set on the subject:
1) Don't drink tap water, for sure. However, whenever you order a glass of water in any restaurant it's ALWAYS purified -- typically out of a 5 gal. container. No need to order small bottles (which just clutter up the trash on this planet). All the ice on the island is made from purified water as well.
2) If your hotel doesn't provide water, just go to Mega (or Chedraui) Store and get a 5gal. jug of your own for about 6$US. It will last all week. Bring your own small refillable water bottles and replenish out of the big one.
3) Some folks swear that by chewing Pepto Bismol tabs before eating, it coats the stomach and wards off the bugs. Personally, I don't like the stuff.
4) I've had real good luck with "Activia" yogurt once or twice a day. Tastes good and replenishes the "good" bugs. In the dairy case at Mega (and Chedraui).
5) "Ectaprim" is the Mexican equivalent of "Bactrim" which is what some doctors prescribe for intestinal distress. It's an antibiotic, so it's best to have your doctor prescribe it for you ahead of time so you are aware of any side-effects (like sensitivity to sunlight). It should NOT be used as a preventative measure. I only take it if I'm hit hard, but it sure gets me back on my feet pronto. Once you start, most prescriptions require you to continue taking it for at least 5 days. That's a MUST.
Good luck and don't hesitate to eat out at the many excellent places recommended on this board. Heck, if you eat out every day in your own home town, I think you're just as likely to come across a meal that will "give ya' the gips"!!!
