Can I survive on even less sleep?

Tell me if this makes sense.

I’m thinking about cutting down on my sleep.  Here’s my rationale. 

I go to sleep sometime between 11:30 and midnight every night. 

I wake up sometime between 5:00 and 5:30 every morning.  Sometimes a little earlier.  

This routine does not vary regardless of vacation schedules and weekends.  I never use my Saturdays to “catch up on my sleep.”

This means that I average about five hours of sleep a night.

But I am almost never tired when I go to bed, and I am almost always ready to jump out of bed go with the sound of the alarm.  I rarely, if ever, find myself wanting to go to bed or remain in the bed. 

So perhaps I could be sleeping even less.  Carve out a little more time to get things done.

I sort of think it’s crazy, but it seems to make sense, too.  Especially with my school year beginning and so much to do.   

No?
