Hi my name is leo I'm a biologist and it's been more than 7 years I'm researching about this subject
My son and 2 of real close friends have this problem so I've been basically trying everything nothing worked for a longterm
After alot of analysis and even sit with them and watch carefully every mouvement of their body
I found the cure
If you make a research even on Google or any forum u ll be noticed that an average human swallow their saliva around 600 to 1000 times per day .
Surprisingly I realised that in all the people suffering from bad or fecal breath the swallowing process rage is really really low or in some cases even absent for hours !!!
Saliva is present in every body even if you feel ur mouth and throat really dry
Saliva has this really powerful antimicrobial and cleaning purpose in our body
The reason is usually neurological
For some reason some people forget to do the " cleaning process " and is result they could finish with alot of fungus and microbes in their system
Fecal breath is just one of the symptoms
So for 21 days ( is the time brain take to get a new habit ) focus all ur attention into swallowing ur saliva twice per minute and to creat a comfortable way to do it
Alot of you may think you already do it properly but if you have bad breath I guruantee you forget to do it !
I can promise that this is the cure for this problem if you pay attention to it
