I have been using the Healthy Wave Mat for 2 and 1/2 months. This has literally been the best purchase I have ever made. Over the past couple of months I have been working 80 plus hour weeks. I sleep on the mat at lease a couple of hours each night and I have had a substantial increase in energy. I am diabetic, but my sugar levels have decreased substantially and are now almost normal. My wife has gotten relief for stomach aches and lower back pain. My son has found that the mat helps him to be in a better mood.
