Anyone have any tips?

After feeling off all weekend I came down with a case of gastro Monday morning. This may sound weird, but I don't remember ever having it before. I have spurts during each day and night where I'm just running to the bathroom and other stretches where I'm fine.

Monday I just dealt with it. Tues morning I rang my ob who suggested gastrolyte. I'm gonna have to go to the gp today for a doc certificate at the very least. In the meantime, does anyone have any advice? The only thing that agreed with my yesterday was a few jatz biscuits.....not the best nutrition...
