I got a mat for my feet for when I use the computer and a semi blanket to lie on in bed. As many others report, I have definitely been sleeping better. I used to have a hard time getting to sleep, and then I would have a hard time getting up after 8 hours because I had not slept enough. Now I fall asleep in about 10 minutes or so.
Also, generally I feel more energetic and am surprising myself at how much faster I am at getting day to day chores done.
I got my stuff from earthing.com. Considering that they sent me a book that was informative, and that they are very, very helpful in emails with any Qs, I feel I've gotten my money's worth. I'll be recommendin earthing and grounding to others.
Don't know, but suspect this would help people with Hulda Clark cleanses and so on - to decrease some of the die off effects.
