I am a nurse and work many 12-14 hour shifts in the emergency department and come home many days completely worn out and achy with headaches most of the time. I also work variable shifts including night shift and could never sleep well until I purchased this product. I am getting such better and the pain in my muscles that would sometimes hang around for days after a 4 day stretch of shifts is no longer there and I can actually enjoy my days off. Any nurses out there with similar issues should definitely consider this product. It is a lifesaver.”
