Yeah, I get what you are saying. But honestly it is not in my head! Everytime I talk to someone they step back or hold their nose. It's like they can smell me a mile away. As far as figuring out where the bb is coming from- I have been to numerous doctors... they ALL tell me the same thing... they say some people just have bb and there is nothing I can do abt it. I don't know where the bb is coming from.. i think it has to do w/my postnasal drip. I just started getting allergy shots and I have eliminated all dairy products from my diet... again I am still not getting anywhere.... i still have the bb... just the other night I was talking to someone and then all of a sudden out of the blue he starts telling me that arm and hammer is a good toothpaste... ???.. ahh...i guess his suttle way of telling me my breath stinks... i have all these medical bills... and i am unemployed.. my insurance doesn't want to pay for any more tests.. i've gone to an ENT, had a CT scan... gone to my regular doctor... gone several times to the dentist and nothing... is there any way for me to do any kind of testing at home? Has anyone else gone through this same experience? Do u know what may be causing my bb?? Is there anything I can do?? Oh, I do drink coffee daily... and I know the coffee makes the bb even worse... however, I have quit drinking the coffee in the past... for like ten days and it made no difference... so now i'm drinking the coffee again.. anyways... any advice suggestions would be appreciated. thanks!
