Why am I awake right now?

Seriously, I have never had issues with insomnia until 2014 started.

I am up for the day around 6:30 to 7:30, and I take no naps. I’m wiped out by 11pm. I have no problems falling asleep. I don’t go to bed full or with a buzz (well, maybe once a week on both). I sleep in the dark.

I wake up around 2:30 or 3am almost nightly, for going on 5 months now. I toss around, get up to pee, then lay here. I worry about things that don’t bother me in the daytime. I get anxious til my heart pounds while I’m laying still. I distract myself with Fluther for at least an hour, and go back to sleep around 5am.

I’m annoyed. I’m teaching my puppy these terrible sleeping patterns. What is up and what can I do?
