I'm glad to hear that you got to the root of your problem!
It's hard for me to believe that lake of acid or access acid in your (our) stomach is the root of the problem, at least for some of us as we suppose that there's many causes for this phenomenon.
I'm saying this from the simple reason that it's a very common situation (access/lake of acid) and FBO is very rare. otherwise, we talking about some kind of a plague..
anyway, it's still very interesting, cause it helped you, and that's wonderful ! don't confuse it with my scepticism.
I just trying to get to the root of this problem... I believe we all got more then one thing that causing the odor, and that many of us probably share the same fault.
that's my opinion, you don't have to agree.
Hoping for a cure, soon, for this terrible thing that caught us in the middle of everything.
