What habit was the toughest to quit ?

I quit alcohol and cigarettes cold turkey about 10 years ago. The cigarettes I weaned off with the help of patches. That was the harder of the two. But after 2-3 weeks, it’s not very hard.

If there’s an urge, just tell yourself, “That’s not me anymore.”, and get up and move. Sedentary is a killer. The devil on your shoulder will get you.
