I have the white tongue too. And the strange thing with it if I oil pull it it nearly disapears and I get a nice looking tongue for 2 hours then I drink a glass of warm water and it is back. Over night it all comes back and its a back and forth like that. If the intestines are filled with that shit, the battle looks helpless as the enemy stands up and push back all the time.
I think we need to boost the own immune system to a level where it starts to kick ass with that shit. I am so tired of that fight.
