Is this insomnia or what?

I love my current job because my work shift is from 1:00 (or later) to 10:00 pm (or later). *Wink* I just wish my shift will stay like this forever. It is rare to find an accounting job with this kind of schedule, where there is no pressure for me to wake up early (unless there are morning meetings or events) and where there is still time for me to spend time with friends or whomever after work.

But one thing that really bugs me is the fact that I can't sleep when I get home. May I be home early (like 11:00 pm to 12:00 am) or late (3:00 to 6:00 am), I still don't feel sleepy at all, except when I'm really really drunk. Like I can just drink and drink everyday for me to easily fall into a deep slumber! Cannot be.

There must be reasons behind this. Let me think...

• I watch TV when I get home. Cable TV offers so much variety of shows that catches my interest. I couldn't resist keeping my eyes fixed on those cool series or movies. So should I just throw away my TV set so that there would be no temptation? Absolutely not!
• I surf the net. I am a total web rat - if you know what I mean. I am addicted to Facebook, Twitter, Blogger, YouTube, PR (know what this is?) and LO (how about this?)! Our home internet connection is open almost 24/7 and we have wi-fi access so I can browse via our PC, my laptop or my phone. No - I can't let go of this addiction.
• I feel hungry at night. Yes, I may not look like a patay-gutom but I couldn't resist giving into my cravings at night - may it be a full meal or snacks. Then after eating, I wouldn't want to sleep due to fear of having nightmares and then die - just like the deceased Filipino matinee idol. So, in order for me not to fall asleep after eating, I either watch TV or surf the net, or both.
• I keep on thinking about stuff. Even if I lose the appetite to watch TV, surf the net or eat, I lay down on my bed but still keep my brain busy thinking about things like work, friends, plans, memories, dreams, fantasies, fears, etc. So what choice do I have?

I seriously need help - professional help. Should I seek counselling and/or medication? But wait, is this the thing we call insomnia? I need to check its definition.

From http://www.medterms.com/
Insomnia: The perception or complaint of inadequate or poor-quality sleep  because of one or more of the following: difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Insomnia  is not defined by the number of hours of sleep a person gets or how long it takes to fall asleep. Individuals vary normally in their need for, and their satisfaction with, sleep. Insomnia may cause problems during the day, such as tiredness, a lack of energy, difficulty concentrating, and irritability.
