keep waking up early

Mnay days now I keep waking up with a feeling like I should stay up around 5 or 6 am. It's really annoying

Can I go the whole day without checking fb

Can I go the whole day without working except to play around on mighty networks

Oh and maybe some fun reading? 

Or maybe I really should take the whole day off. It's frustrating that I have a lot of resistance in doing the reading on weekdays and the minute I decide to truly take a full day off, my brain says what about the books
