I have a very similar story. Some of the very things you described in this post have happened to me. I have extremely bb and it is destroying my life! I have gone to the dentist and several doctors. Everyone tells me there is nothing wrong and I can't do anything about it. This is destroying my life. I am at my wits end right now. I have quit school, quit my job, stopped socializing. All I want to do is curl up in a ball on the couch and cry. I recently went to the east coast for a visit and the postnasal drip which I believe is causing the bb is worse and continues.... I think in my situation though it may be more than bb as well... I think it might be an overall Body Odor like you described. I have tried everything!What can I do aside from flossing, brushing my teeth/tongue, mouthwash, nasal drops etc ?? I have purchased over $300 dollars worth of Therabreath products and they do not work! I am so upset and frustrated. What can I do for the bb and Body Odor ??
