I've tried many different supplements including herbs, but the most important thing for me is diet. My symptoms are gas, burps, and my period is missing. When i follow the diet my gas disappears, but i still have this burping thing and I haven't seen my period since august. I've been on the diet since juli 2013, was improving, but then i started with buckwheat again and my period disappeared again (it was back a feew weeks into the diet when i started it for the first time). Didn't realize back then that i must be on 0 carbs. So now I been on 0 carbs since februari and 10 Days ago i started supplement with S boulardii.
