Sleep deprived

Yeah, another sleepless night. And you would think that after last nights activities, I would be content in the arms of the stunning woman who is still warmly sleeping in my bed.
I tried to sleep. She made herself comfortable, wrapping around me, and I listened to her breathe for a long, long time. My eyes never closed.
So here I am. Trying desperately to figure out why I can no longer sleep. I have no worries. I mean, yeah, I got the normal family problems but nothing that's been occupying my mind for more than the ten minutes or so it takes to have the problem discussion.
I've been writing intensely. No problems there.
I don't know, but whatever it is, I hope it starts talking to me or something.
I think I'm losing my mind.
