Saving up my sleeps

For my 8:00am class, I try to get up at 6:30am every morning so that I have time to get ready, eat breakfast, briefly read the Bible. However, my body naturally feels rested after about 8 hours of sleep. It's so frustrating though, because I get up early but then I get really really tired in the afternoon. I used to nap, but today I forced myself to stay awake so that I can just go to bed by 10:30pm.

But of course, I can't sleep. :(
