I keep folks' words who have lost their quits because of drinking, and like to share them with the community from time to time as cautionary tales: Here's one from my collection (and there are many):
"I was going through a stressful time and I was drinking with a buddy and bummed a few cigarettes and the next day I bought a pack. I went on smoking for 33 years."
Please be warned. Don't let it be YOU I'm quoting sometime in the future!
A quit is a terrible thing to lose.
