Thanks for your post. I enjoyed reading it. You sound knowledgeable and level-headed. I had candida which caused a lot of belching. I finally got cured of it but was surprised that I still had occasional bouts of belching, not as much but still more than normal. I figured out that my initial bout with it was mostly candida but this last round was probably SIBO. One of the keys to getting cured of my candida was taking probiotics (both capsules and fermented veggies) PLUS taking prebiotics (lactulose and Galactomune). When I recently started spacing out in time my dosing between the probiotics and prebiotics the belching stopped. I'm pretty sure that when I was taking prebiotics 6-8 hours after the probiotics, it was not enough time for the probiotics to get to the bowel (large intestine). So the probiotics were being fed while still in my small intestines, hence lots of belching. So now I take probiotics at 6 a.m. and prebiotics at midnight. Problem solved. Hope this helps. Ask me anything. I'll help you as best I can.
