Time change sucks!

Why does time change suck? I am at home today since I have no job currently, I was able to sleep in until officially 9:50 am and I still feel tired. I went to bed around 1am so that means that I got over eight hours of sleep. That should be enough right? Nope! I still feel tired and if I had a job to go to, I would definitely need about two cups of coffee before I can function right. I hate time change!
