Hi for past few months my sleeping has got worse and worse. I go to sleep ok most of the time but usually wake up a couple of hours later with aches and pains in my arms and back, a dry mouth (even tho I have drink alot of water and have a bottle next to the bed) and a stuffy nose (not a cold though) sometimes I wake up with pins and needles in my arms. Does anyone have any idea how I can get a good night's sleep? It's not the mattress as I've had it a couple of years no problem.
