so I stopped drinking
You made the right move.
It is not a question of intelligence or stupidity though, more one of susceptibility.
I can take spirits or leave them, others find it hard to stop drinking.
I opened up an old bottle of Cognac last night and had a few sips along with a couple of Stella Artois:)
To me, that is sensible drinking.
You have to be careful with alcohol, especially spirits.
I knew a few Polish alcoholics as I am sure you all have.
It never ends well.
