having heavy lids is torturous. all i can imagine is my head resting on a pillow all snuggled under my duvet.. I read somewhere that if you're seriously in trouble staying awake that you should focus your eyes on something red.. the bright color is supposed to trigger something in your eyes and brain that will make you feel more awake. sadly, i've resorted to to this method several times at work. still not too sure if it works, but at least it gets you moving.. hehe
