Just forgot to add on the difference or not between cigarettes and alcohol, analysing is OK but as I said, alcoholics do everything in excess. If you keep analysing something over and over looking for an answer when maybe there isn't one, or the right one, or looking for it is not helpful to you......then maybe it is not a good idea.
Alcohol is "cunning, baffling and powerful" and has been known to distract alcoholics in all sorts of ways which end up with them picking up the drink again.
I was a 40 to 60 day smoker and gave it up relatively easy compared to alcohol. But I see alcoholics in AA, who have quit drinking but are smoking themselves to death.
We have a saying in AA about concentrating on living in the solution rather than the problem and that's how we can stay sober.
