Speaking of coffee and alcohol, I quit those the same day I quit smoking. Haven't had a sip ever since.
I had a soda-based caffeine addiction that I quit over a year ago. Before that I was buying caffeinated mints and other sources of caffeine. Cold turkey was the only way to do it. I did try the "cutting down" thing with the Mountain Dew and such, but it did not work. When I went cold turkey, it worked. I haven't had a caffeinated drink or candy in over a year after drinking caffeinated beverages my entire life.

Did you go to jail or rehab?
