It's 3:09 AM, why am I still awake?

Insomnia's an odd one to figure out.
Is there something on my mind?
Bills? No. Paid up this month.
Work? No. Going OK.
Relationship? Ha. As if I had one to fret over.
Nope, 3:09 AM, wide awake....and blogging.
Can I take something?
Sure.
I don't mind being a zombie in the morning.
Or beating my alarm clock with a hockey stick to shut it off, before I angrily go back to sleep.
I've always been a night owl though.
Maybe it goes back to the old days of clubbing.
Staggering in around 4 AM, pissed out of my mind.
Collapsing in a heap.
Gritting the teeth to get through the workday.
Swearing to yourself that all you need is an hour's sleep, and you're fine.
Deciding to head for home, have a nice meal, and get a good night's sleep.
Whazzup?
WHO's playing WHERE?
I am so there.
I'll just have a beer, maybe two, and no more.
Tsk, tsk, and it starts all over again.
