I'm trying to see if any one has managed to train them selfs to only sleep on their back. Im one of those that rolls in my bed at home but backpacking it can get quite painful. I've tried putting pillows on either side of my head.. It failed.

The main reason I'm doing this is so i can do away for the need of a pillow when I'm out. It's always a pain! And I can shave the weight.
