Ok, it's 6 in the morning. Haven't slept yet. No reason, really. If there's no reason to get out of bed during the day, I guess there's no reason to go to sleep at night.
When I was awake for two days this weekend, I told myself it was for the best, that I'd be correcting my sleep pattern. By Sunday, things would be back to normal. I got out of bed today at four in the afternoon.
