Getting up

I've had some issues with getting up with my alarm. I can get up for work but not so much with everyday life. School starts on Monday and I have an 8am class that I have to be alert and awake. To prep for that the last two days I have gotten up around 5:30am. Which is really early. and I'm wondering if that is too early, or is my body just not used to running on 6-7 hours of sleep? Time will only tell.
