Wayne, Are you still earthing? I think it is great, really helps the pain and what else could be helping the OI? I got the pad first and have it under the computer desk...helps with EMF. I then ordered the half sheet which you put across the bed, so my husband gets the benefit as well. Really amazing, I would recommend it to anyone. It is also quite cheap compared to others things we do. I read that the sheet does wear out in 3-4 years. I wash it and dry it..okay for that. I am falling asleep faster and sleeping better as well.
