Ya know... the well water could very well be slightly "contaminated" as of late with all the warm weather followed by the heavy rain.

May I suggest boiling the well water? You can always use bottled water for drinking for a while.

Of course, jello is good (no red couloured stuff), as are clear fluids, no dairy, etc, etc... the regular advice to help clear up a bad case of the trots. And, after it settles, some "pro-biotic" yoghurt to get the good beasties going again.

In any case, I hope the doc stays on top of the situation and things work out well in the end. Yeah, I know... >:-)
