I know that feeling well. I quit on Dec. 19, 2010, so I was in pretty much the same boat on my first New Year's. My addiction was seizing on the date to make me think I was missing all the fun. Some fun. Checking my eyes for signs of jaundice, fearing I might never quit. I remembered how the idea of going even a week without a drink seemed as far-fetched as summiting Everest.
You aren't missing anything. You are on your way to the life you deserve. That's something to celebrate, starting with how good you get to feel when you wake up on Jan. 1. You're on your way to an awesome 2014!
