Ive been suffering from Bad Breath my whole life. It seems its worst after I drink alcohol. I will tell you why you have bad breath. Aside from poor hygiene and TMAU, you probably have a parasites in your intestines. They will kill off your good flora and give you a yeast infection. I have smelled my whole life, tried every diet under the sun, tried probiotics, but nothing worked until I killed my tapeworm. When it died, my breath smelled like nothing! Things around me didnt stink either. If you smell and dont know why, then invest in some Zymex II, Humaworm, 4000mg doses of CoQ10 with Fish Oil, Ozonated Olive-Oil with L-Cysteine. If I can help at least 1 of you then this post is worth it.
