Okay, I'm in a new apartment and I'm having trouble sleeping at night. I think my sleep cycle is messed up.

Back at home, someone would wake me up EVERY single night to go to the bathroom. It happened around 2-3 a.m. Now I'm not at home and no one is going to the bathroom at that time, yet I wake up every night at that time and have a lot of trouble going back to sleep. I end up taking a nap or sleeping 2-3 hours in the day time, which is not good, especially with classes going to start soon.

I have googled and searched on the internet to find nothing to help me.

Does anyone here have any ideas or do I need to go to a doctor about this?
