hey sufferer, iknow the cure to bad breath, if its the case of a coated tongue.....but i have not tried myself too....i should say i have read the cure to bad breath...i could not get the cure in my hands cause i live in india.its not available anywhere in India.anyway, the cure is known as Grapefruit-Seed-Extract grapefruit seed extract.it should be the liquid form, not the tablets or capsules.....GSE liquid from nutribiotic is the best i heard and it has not disappointed any one. it kills the harmful pathogens directly...but i'm unfortunate that its not available in India...but you please give a try if you could ind it and let me know.GOd bless you!
