Sleeping disorders?

Damn. I think I messed up my internal clock again. It's 4 am and I cannot seem to fall asleep. I have thought of every little thing except of falling asleep.

Seems like that sort of thing always happens to me over the summer period. Is it the weather? The temperatures? The roommate? Or just my own thoughts? Or is it just my hangover that came unexpectedly early after the late night snack and drinks.... who knows. One thing is for sure - not tired at all.

I called my boyfriend, but no improvement. We chatted a bit but he didn't have anything boring to say so I didn't get really tired. Anyways, no complaining. Gotta improve my lifestyle.
