18 hours?? Wow.

I sleep about 8, but often only get about 7 or even 6. On Tuesdays I start work in the afternoon though so I'm lucky and get about 10 if I sleep in. I mostly need to sleep more cos I get tired a lot -_-

Oh and, how well I sleep mostly depends on how I'm feeling, if I'm happy and relaxed I sleep very well, if I have stuff on my mind, then less so.
