What is your vice?

I think that all people in this world have things that they are addicted to. Things that they feel they are unable to live without. What are these things for you? What do you feel like would make your life have a lower quality in some way? For me it is Pepsi (an addiction that I am trying to slowly cut out of my life) and also cigarettes (a dirty habit that I picked up as a teenager and have never been able to get out of yet, although it is less than it used to be). Share your vices with me and let me know if you are doing anything to try to eliminate them from your life.
