OMGosh, I have the same exact issues! My Gastro. is not very knowledgeable about SIBO and I am even surprised he knew to do a breath test. I live in Oklahoma where there is very little concern for health issues, so getting help is impossible!! He keeps treating me with X drug, like you (very expensive, I have no insurance), once it's gone, the issues starts again! It's like a viscous cycle and meantime my life sucks, low on energy lay around alot and afraid to eat for fear of an episode of stomach bloating. SOMEONE has got to get a hold on this and help us ALL!!
