No coffee here, but frankly I'm surprised I'm still awake! I've been up since six this morning and I'm really not that tired. I'll be feeling it in the morning though.
Coffee normally doesn't affect me like it does my parents. It usually wears off pretty quickly.
I had a glass of wine earlier and it almost knocked me out. If it wasn't for the uncomfortable chair I was sitting in I would have been out like a light!
