I was a bit hesitant to go with the grounding sheet at first though my Wife said to me it's worth a try. I have had Sciatic pain everyday since March 2013 and the pain had become a friend I no longer needed . I was taking Anti this tablets anti that tablets 3 times a day I felt like a lab rat I've been on the earthing sheet for 6 nights and it's magic my pain is 100% better and my wife tells me I no longer snore. Please if your in pain in any way try it you'll be amazed it's worked for me regards Richard.
