My observations

I too no longer have a coated tongue.

Sleeping less. Use to sleep 9 or 10 hours. Now I can't sleep past 6 or 7 hours. Seem to have more energy during the day.

I notice a couple of other improvements in my health, but it is too soon to make the connection. Eczema on my elbow, and my Ulcerative colitis. Both seem better, but they have come and gone before.

Been doing 4 min X 5 for about 4 or 5 days. Tweet
