a question about ingesting food grade medicinal clay

[brightlotusmoon]

I just wanted to confirm something, as my favorite toothpaste contains Montmorillonite clay mixed with Himalayan crystal salt, and I tend to swallow it after brushing:
Is it true that I should not take any medication within two hours of ingesting Montmorillonite clay? Is this true of White Kaolin clay as well? Or all clays in general?
(I've discovered that swallowing my toothpaste has been incredibly beneficial when I have diarrhea or cramping, so I like it even more.)
