sorry to hear about your problem. Your doctor didnt recommend that you do anythign about this? he didnt have any ideas? personally ive really been fed up with western medicine ever since ive tried to get help for my BO/BB.
i dont know what to tell you to be honest other than hang in there and hope a cure comes around. I too have to chew gum/suck on mints all day, and youre right, its horrible - it really impacts the way i interact with people and its very debilitating.
google some stuff and see if you can find anything on it, im not familiar with your condition.
good luck and take care!
