What was the hardest for you to quit/stop doing ??

Smoking. I quit cold turkey when I was 36 years old. Even ten years later, when I saw a package of cigarettes someone had just left lying on top of a pay phone, I said to myself, "No one would ever know!"

But I also knew myself...and I knew that if I smoked even ONE cigarette I would go right back to chain smoking 3 packs a day.
