I've never been much of a drinker but since surgery, I've had a couple of sips... really just a few sips. And, wow! They felt awesome! I felt like my eyes glazed over and it was like... wow, this is nice! Such a nice mellow. Just thinking about it makes my eyes glaze over. Yum....
So.... I know that my body is responding differently to alcohol post surgery. Way differently! Like the other commenter said, I'd be REALLY careful! Sounds like brain based addiction. After a surgery, I was given Oxycodone. Nice stuff... I liked being on it. Liked the relaxed feeling I got from it. But when it was time to stop taking it, it was like a siren song in my head for weeks! I still have some left over and the surgery was about a year and a half ago. I was able to stop, but I had to actively resist.
Sounds like it might be time to go full abstinence. I really hope you are able to work through this and not fall into that hole! Because it's a dark one....
