So everynight, I am always waking up at 2am...4am.. or even 5... Sometimes 2 times a night..

It's becoming very annoying because I am tired every single day and I don't think this is healthy for my body.

If I don't have school or work the next day.. I stay asleep until 12 in the afternoon

I eat healthy, I don't booze.. I excersie...

Can someone give me some tips.. I can't stand it anymore... should I try rearranging my room?
