Last year I gave my first real effort to quit drinking. I was a light smoker (I guess), smoking about one pack a day at the most. I kept up the same routine I had just without alcohol. Eventually after about 100 days or so I one stressful event led me out to get a beer. Of course, smoking and drinking had always gone hand in hand. I really think I was just tricking myself the whole time. I wasn't really letting it all go because I kept smoking.
This time, 88 days ago, I stopped both at the same time cold turkey and haven't looked back. I truly believe I had to let them both go in order to really discover true sobriety. I have no chemicals in my body that affect me and no habits that are related to one another. Smoking reminded me somewhat about drinking, and I believe drinking would remind me of smoking.
