the cure for my BB was simple: a tongue scraper. i would take it and put it on my tongue as far back as i could get it without gagging (and sometimes i would gag), and then press down and pull forward. rinse off the tongue scraper and do it several more times. then brush as usual, and brush the tongue.
the effect was dramatic and instant. i have done it every day for the past 3 years, and no more BB, except when i come down with a cold or upper respiratory / sinus illness.

i hope this helps someone!
