I'll give you a real-world example:
I have 504 days sober and I love it.
I feel fantastic and life has gotten better and better.
This morning I ran a 25 mile relay with some friends.
At the finish, a lot of folks were drinking beer.
At one point, it flashed through my awareness; 'a beer would be good. I bet I could have a beer, no problem. This whole sobriety thing is probably an overreaction'
