4myhoonie, I just wanted to say that we've recently had a stomach virus, and it was REALLY bad. Mostly because it lasted forever, and nothing helped it. Nothing. Not probiotics, not water kefir, not apple cider vinegar, not colostrum, etc. I even tried taking some pascalite clay after I was past the worst of it (during which time you could not IMAGINE trying to get anything down), and I can't honestly say that it seemed to make any difference.
This stomach virus really frustrated me, because in general, we can either entirely prevent getting sick, or get over it very quickly. I don't know what we're doing wrong, but we got SO sick, and it lasted and lasted and lasted. It was no fun.
I sure would like to find out what would have helped! Let me know if you find anything. Hope your family is well soon!
