Home Remedy - what is an at home remedy for diarrhea and cramps as well?

I routinely drink two cups of black coffee every day. It always triggers a morning bowel movement.

For this reason, if I were experimenting with home remedies for controlling diarrhea, I would eliminate coffee for a couple of days & make a record of the day(s) I went coffee-free.

If coffee-free living didn't help, I would record it on my calendar then move on to systematically eliminate one food at a time that I routinely eat every day or almost every day. My experiment would include bottled water, vitamins, and both prescription and over-the-counter medication.

I base this post on my own successful experience with eliminating certain foods that I suspected of causing urinary incontinence. I found out about food elimination trial-and-error on a blog posted by board-certified urologists. I can't recall the source.
