Congratulations on your 4 months. That is fantastic.
As for the intrusive thoughts...Here is what I did: It's basically AVRT.
I knew intellectually that I couldn't ever drink again. So any thought that conflicted with that is an alcoholic thought.
"Oh maybe I can have a glass of champagne on NYE".
Right. That's a stupid, alcoholic thing to think. I guess I'm still an alcoholic lol".
I would literally run that through my head. 'Calling out' the thought for what it is. Nonsensical, alcoholic BS.
I tried not to get too upset by it. Kind of faked it 'til I made it.
I agree with Dee though and wonder too where you are wrt your marriage etc.
Sending you good thoughts and hugs.
