I think I have insomnia seasonally, i.e., only when I come home from school.

Every time I have a college break, my sleeping habits always take a turn for the worst and I wind up going to bed at around 4am every night (well, morning I guess) and waking up at around 2pm. I don't want to sleep my entire day away, but I have a lot of issues trying to fall asleep. 

It's strange, because when I am at school my sleeping habits aren't usually this out of whack. I am pretty sure it is because I have schoolwork, jobs and other various collegiate things to worry about, and I tire myself out. I just find it odd that somehow during summer and winter breaks, my sleeping habits completely change and I have serious issues trying to retire for the night.

I've tried going to bed earlier, but I wind up tossing and turning until 4 a.m. and then falling into a deep slumber until the early afternoon. This has to change, friends. Sometimes I even get tired again during the later portion of the afternoon and take a short nap from about 5 p.m.-6 p.m. When this happens I usually try and whip myself up a cup of coffee to keep me from sleeping, but I think my system has decided that caffeine is no longer suitable to keep me awake for long periods of time.

From what I understand, this happens to quite a few college students when they come home from breaks, so I am happy to report that I am not the only one who is suffering from this nighttime plague. A forthcoming problem with my sleeping habit (or possibly the solution) is that I am starting my summer job next week and I don't want to be tired from my weird sleeping hours (OR it could encourage me to try and get to bed earlier. Hopefully.)

What should I do? Does this happen to you sometimes?
