A problem that has become worse; almost chronic in the past few months is waking up in the night or morning to find that I am asleep on my side and one arm is completely numb and limp due to me cutting off the circulation. It's gotten to the point that it's happening almost nightly, and its started to infringe on my sleeping pattern and dream recall. I generally fall asleep on my back, and have become more aware of what position I fall asleep in the past week or so, but still find that I wake up in this position, with my arm numb.

Anyone know how to stop this from happening?
