I agree with Rachel on her third suggestion especially. Try to avoid looking a the clock. That makes it worse because you keep reminding yourself that you have to be up at such and such hour and it adds to the cycle. I usually read, flip on the TV or go on the computer. I can't walk around too much or the dogs think it is morning and time to go out. Three AM is not a good time to let them out as that's when there are critters in the yard that *need to be barked at.*
