Here's some food for thought for you: Did you know that when you sleep at night, your body releases toxins from your liver, and that they come out coated on your tongue?
( I know, it's not a pleasant thought, but your body has to get out bad stuff somehow!)
And did you know that if you wake up and take a drink of water, or swallow, you reintroduce all those toxins into your body that your liver worked so hard all night to eliminate? Interesting, huh?
So make it a point to brush your tongue every morning as soon as you wake up, before eating, and give your liver a helping hand! ;)
