The three things that I do that I just can't help and could probably live without.

Cloves.
Clove cigarettes are the only thing I ever really bother to put into my mouth and breath through. Or they are only things that I am willing to pay to do. Marg and I are addicted to these little bundles of cancer filled joy, but I use the term addicted loosely since we make a pack last a semester because we are still poor college students.

Gin.
I only ever drink gin unless I'm drinking some fruity beach cocktail. It's a family thing. I've only ever grown up with gin and red wine in the house and since my mother doesn't drink much I had to learn to drink from the gin drinkers of the family. Gin is by far the best, who doesn't enjoy the taste of Christmas in a bottle?

Biting my nails.
Not really a vice, but it is something that I do that I really shouldn't be doing. It's a bad habit that I picked up at a young age and haven't really ever been able to curve. I can go days without doing it and then something sets me off and I have no more nails. Right now my nails are the longest they've ever been, it's also a while since I haven't been stressed out.
