Reply #3: hmmm... I suspect something else was at work

1) Beneficial gut bacteria are in your colon, not your stomach or small intestine. (Which isn't to say that bacteria can't live elsewhere in the GI system--e.g., H. pylori--just that the healthy ones are in your colon.)

2) Half an hour wouldn't have been long enough to get the yogurt to your colon, much less repopulate it.

3) I don't think (although I don't know for sure) that alcohol would make it intact to your colon in any significant amount; it'd be absorbed and metabolized in the hours that it takes things to get from your mouth to there.

I wonder whether it was the protein in the yogurt that helped, especially if it was unsweetened yogurt. Protein is nice for stabilizing blood glucose levels. Or maybe, if you hadn't been eating enough lately due to feeling crummy, just eating something good for you did the trick.

All this is JMHO, of course. Whatever the reason--I'm glad you're feeling better!
