Does anyone really get 8 hours of sleep a night ???

I can not stand it when I am all nice and sleepy and then I go lay down and I am wide awake !!!! As much as I would love to be one of those people that can sleep 8 hours (as it is recommended by doctors) I am just not!!!!!!! I am doing good to get a soiled 4 hours of sleep. I usually wake up about 6 times a night ... why ? if anything makes a noise I am up ! I am a light sleeper were as my husband is not a light sleeper, he would not hear it if a train came through the house. As long as you do not take his covers off and turn on the light then he will sleep through anything else ..... MAN, that must be nice !!!!!!!!!!! For me to sleep like that I have to be heavily medicated.
