@rangerrebew Here is a miserable story:
I was in Mexico and know about the water, and drank bottled water but that didn't help. I went to the mountains where silver is made, on a sight-seeing bus. While in that town, a sand storm that happens every day along with rain happened. I had sand in my hair and all over me. On the way back to hotel I was getting sick, knew diarrhea was going to happen. Then, the bus broke down. Had to wait for another bus to come get us.
I was really sick by the time I got back to hotel. I didn't know whether to get in shower to get the sand off me and out of my hair, or sit on the potty. I got in the shower to quickly get clean, and the diarrhea happened while in the shower. Yes, that is a terrible visual you just had. When I was clean and the diarrhea was over, I took Pepto-Bismal, as I had that with me, and got in bed miserably sick. Others with us were sick and we gave them the Pepto-Bismal bottle.
Have been to Mexico several times, and got sick each time while doing my best to not get sick, but that time was the worst.
