Uh…if you feel this is too much TMI, that title should have been warning enough.

I’ve been having really, really copius and stanky gas since my c-section 6 weeks ago. At first, I thought it might be due to some wierd intestinal bacterial imbalance caused by all the IV antibiotics I was on at the time. But it’s been a long time. And the stank is not getting better.

The only other thing that changed was that I started taking Brewer’s Yeast (2 tablespoons a day) for protein and b-vitamins. I really like it - it makes me feel much better. But could it be the stank culprit? Why?
