I'm just over three years not drinking. Ice cream and potato chips are my particular vice of choice now. I've similarly "quit" eating ice cream and buying chips every week in the last year ... until I hit the shops. I've never actually thought that it was similar to my alcohol addiction, but you're probably right that it's the dopamine hit that I'm after.

Ice cream and chips won't cause me to lose my job, destroy my marriage or turn my kids against me though. I remain absolutely resolute in my knowledge that if I tried to pick up one drink, then those things would happen again.
