I've always been really good about cutting off bad habits when they started to approach addiciton: food, alcohol, smokes. I don't like being indebted to a habit. I don't like that which I can't produce from my own being. In other words, if I was stuck on a desert island I'd still be able to find happiness and faith in life. No chemicals needed.
My biggest current vices are daydreaming, procrastination, worry, music obsession. I wish I had a spending habit, but I haven't had a dime to myself since last spring so that ain't happening anytime soon. That's why I daydream so much. It's all I have, haha.
What about you? What are your habits; your vices? How do you 'get through the night?'
