The quest for sleep

I've always known I needed more sleep and I always say I'm going to try to get more of it.

I never do.

Would it be possible for me to set aside 9 hours a night for sleep? Meaning that 9 hours before my planned wakeup time I'm in bed.

I figure I need to allow some buffer time for actually falling asleep once I'm in bed.

It seems so easy, yet I can never do it.

WHY?!!!!!!!!!!!!!!
