the same about physician :). Anyway - i'm not a doctor, so it is just a personal anekdot. To me it was very active fermentation and resulting excessive unstoppable belching (impacting/stumbling the natural breathing movement of the chest/lungs and that breathing problem made it very hard to for example concentrate or to get to sleep, etc.), fatigue and brain fog. Reading Internet made it pretty clear that yeast/candida is the primary (and basically the only) candidate. Antifungals drugs seems to be the medical way to go. On the other side - giving that candida is the natural tenant inside our GI system, it seems to me (again, i'm not a doctor, it is just my understanding) that full "cure" isn't really possible and one can only control the issue. Giving that people reported very different results with those drugs and those drugs may be heavy on liver i decided to go initially with more natural alternatives. I'v been so far fortunate that it works for me. Specifically well known natural antifungals - garlic (as pills because real garlic smell is an issue at home and at work :), apple cider vinegar (for me it works as 2 tablespoons diluted in a glass of water 2 times a day), ginger (several cups of ginger tea during the day. Also instead of apple cider vinegar i frequently use vinegar based tonic like Kevita, specifically the "Tumeric Ginger" one. The tonic also contains probiotic cultures and that works great for me). I use all 3 of them - garlic, vinegar, ginger - as at the beginning i noticed that when using only one the yeast seems to adjust after some time and the issue starts to come back. In general it seems very individual, takes some time and experimentation. It took me several months to develop my regimen mentioned above and achieve current stable good results. Again, i'm not a doctor and this is just a personal anekdot.
