Try this: take a deep breath. Retain it as long as possible. Notice carefully everything after that point. Tonight when you brush your teeth, review what you observed. After you brush your teeth but before you rinse, lift your hand and brush them very carefully again with a toothbrush that is imaginary. Now pick up the glass,turn on the faucet and watch it slowly fill with cool, clear water. Drink as much as you want, until all your thirst is gone. Notice the difference this makes.
