I get yeast overgrowth, so I have to have "Yeast Cleanse" to kill them. And yogurt, and probiotics, to help correct it. I just had a round of antibiotics a couple of weeks ago. I guess it will still be awhile before I can get rebalanced.I have the same problem. Not sure what causes it but I think it's bacterial overgrowth in my stomach. You might want to look into that. Beer can cause it to happen among other things. Probiotics are a good option along with natural yogurt.
Much love!
