I still get these all the time!
Really ridiculous stuff such as 'If my wife left me and took our son, I could drink myself to death with moral impunity' or imagining our tiny son as an adult travelling miles to rescue me from a relapse in twenty years time!
I like to think that the fantasies have become more extreme and distant (as opposed to 'I could just nip out and get a bottle' type stuff) because - as time goes on - I am much more confident that drinking is behind me. I made it into a sort of game at first & found much joy in 'catching myself out'.
Sorry, waffling. My point; I reckon the thoughts don't stop, but that their power is greatly diminished over time.
Sounds like you are doing great to me!
