I drink way too much caffeine. Not sure that is a specific habit as much as a personal choice. Oh it's making this weird sound when my throat itches! I can't describe it, but it is annoying. I try not to do it, but inevitably when my throat is itchy, I tend to do it.
Edit: I'm too slow and too verbose. I used to, but haven't in a while. The one I played was Yahtzee! Got bored with it though.
What is something you have put off for a while and would like to do/take care of within the next couple of months?
