Sorry to hear that! I have the same issues including BO. I decided to go to a Urgent Care Clinic in my area. Instead of me telling them what i think it could be, i exaggerated (that my tongue and thoat are white, and food taste nasty when it touches my tongue) my bad breath issues. He gave me something called Liquid Phenergan DM for Allergies. It did nothing for me! But it's only been a couple day's. Something that did hekp he gave, was a Mouth Rinse for Yeast called Liquid Nycostatin (swish and gargle 1/2 tsp 3tms daily). That has helped alot! Went to a Party lastnite with no reactions from friends.
