In High school when my insomnia was even worse than it is these days, I used to only be able to fall asleep on my stomach... Very comfortable way to sleep apart from f**king your neck up... Always wanted a massage / chiro bed to sleep on as the face hole makes it perfect... Obviously in a standard bed form though.. These days if I get in bed and try to fall asleep on my back, unless I'm exhausted, it's not gonna happen.. On my side is the best bet but usually wake up sorer... Those tempur mattresses advertise themselves as moulding to the body etc, and I think they're in the $10k+ sort of price range... (don't quote me on that as I've never looked into them, just what I've heard) Either way, assuming they aren't cocksuckers and honour the warranty on mine, I'm not looking forward to choosing another one. Granted my body is a piece of shit so I'm probably never going to wake up feeling good... But hopefully I can achieve a less f**ked up feeling than I've got now
