How much higher are you hanging your feet? I like mine about 1-2 inches of difference from one end of the hammock to the other. It only takes a little to keep you from sliding. You may also want to try a small pillow if you aren't already. It makes a big comfort difference to me. And try different sized ones, to small seems useless and to big makes things miserable for me. But when I found the "Just Right" one I was set, not even a warm bowl of porage or a angry bear will get me to wake up.
