Yeah, I should probably get the diarrhea checked out by my doctor. I am sensitive to diary products (like milk, yogurt, ice cream, etc) yet I still eat them so that definitely contributes to my problem. And I do eat the yogurt with the live bacteria thing because I've heard lots of good things about it (even though I don't really know it's purpose).
I have an interesting stomach. It's very sensitive to almost anything besides fruits and veggies and bread. I really have to plan my days around what I'm gonna eat because I never know how my stomach is going to react.
