I drank a six pack of heineken light from around 11:30 until 1:30. Then I switched to liquor and coffee. Coffee is part of the problem. Inability to stop thinking is the other part.
I don't do this often. About once every three months. Believe me, I wish I could go to sleep. I just don't want to be sober right now, and sleeping means sobering up. I need to, since I have things to do today, I'm just not ready for that yet.
