This Professor said that halitosis is obviosuly a real
problem but that in his longterm experience it is almost impossible to cure. I was absolutely shattered and demoralized. Nevertheless, so as to not discourage me, he ordered a routine detailed blood test, hydrogen breath test and a gastroscopy, the latter two which I am due to have on 12/July and 3/Aug respectively.
He also prescribed Omeprasole, one of the PPI blockers, saying that it could be the bodys acidity that is causing it.
