Q: I had diarrhea today, it was almost completely liquid. I hadn't had breakfast. I started the day with 2 big vitamins, and then had sushi with my mom. My mom did not get diarrhea, and we ate the same stuff. I did get diarrhea. I am also about to start my period, but I've never had diarrhea because of my period before. What do you think the cause was? And what do you think I can do to stop it? It's controllable, but annoying. while spicy food may be the culprit in some cases, I didn't have spicy food, except for mildly spicy salad dressing. I didn't even have much fiber.

A: most likely a combination of overdosing on vitamin C and the sushi.
