So, ive taken antiboitics for bacteria, and that didn't really help.

im taking omeprazol now because they think it could be because of reflux, but thats not helping.

i brush twice, been to see a dentist and hes said nothing to do with my teeth.

theres always a bad taste in the back of my tounge, a little like vinegar. After i eat anything, i get a bad taste that lasts an hour, and halitosis along with it. Im constantly chewing gum when im around people... 

when i wake up, theres a white coating on my tongue towards the back, and always theres halitosis. really annoying!!!!! i cant talk much because of thisssss.

how do i solve this issue?
