Hi! I was just reading that a white coated tounge is actually toxic waste being eliminated from your body bit by bit-- and you will find the coating the strongest in the morning.
I switched to Vegetarian-- as I still eat free range organic chicken eggs and unpastuerized raw goat's cheese (which never gives me mucous like the cows milk does and still tastes great in salads)
When I stopped eating meat in 2005, I also got alot of the white coating on my tongue. It was a little scary. I also broke out around my mouth and cheek area alot-- alot of white heads, and yet I keep my skin clean too, but it looked like I didnt to others. This was because old mucous and toxins were leaving my skin.
Just drink alot of herbal teas and good water in between meals to help flush out toxins and start doing some colon cleansing as well- When you clean out your colon you will notice less of these detox symptoms as more toxins are able to escape out into the bowel movements and urine instead of being backed up.
Eating more raw fruits and veggies, unrefined wild rice dishes, raw nuts and nut oils, olive oil, coconut, you will really have incredible bowel movements where you dont need to keep using psyllum husk, etc.
