I think you might have to find out what's causing it first, especially if the imodium isn't working. I hope it's not a bug. Can it be a reaction to any of your meds? I was feeling pretty bad when I woke but it's leftover from what I was eating yesterday I think. But several secondary aches and pains and stuff have come up.

Let us know how you're progressing. I would just think of something I felt like eating; toast or something to help the nausea, and hope it also helped the other end. Drink plenty of liquids for the diarrhea. I'd be doing warm, comforting stuff like soup/chicken broth.
