Oversleeping is a sign of depression and causes a bunch of other side effects.

I am in college and have classes only twice a week. I packed all of my classes on two days because I thought I would get a part-time job to work on the other three days. The job feel through and now I am just going to school twice a week, working out four times a week, and going out on Friday/Saturday.

Question: How much sleep is too much? How do I regulate my sleep cycle to remain constant?
