A few years ago I took a quick long-weekend trip to Puerto Vallarta. I didn't do anything risky. My last day I went to a restaurant and had an American style breakfast. It was a really nice and clean restaurant, even run by Canadians. I had French toast, bacon and eggs and a glass of orange juice. The food tasted good but just as I was finishing, something in my stomach wasn't feeling right. I couldn't finish every bite. I decided to go take a walk to the beach figuring maybe I'd feel better in a few. It only got worse and turned into really bad nausea. Unfortunately my flight back home was within a few hours and I was feeling so sick in the stomach going to airport, waiting in lines, waiting for the plane. I probably took about 4 or 5 pepto tablets within a few hours. That's probably the only thing that stopped me from getting violently ill. It was terrible! I don't know what caused that reaction. For the next few days my stomach felt unsettled. I had a margarita at a beach bar the 2nd day and it had some ice in it I think. I don't know if was something in there that caught up with me or what. That's my only experience getting sick in Mexico in the several times I've been. Bu this will be my longest trip there and I dread feeling like that again, but I'm just going to brave it anyway because I love travel.
