Glad you're here, Sven, and that you have started this post.
I probably drank more than you do, but you have drunk more than twice as long as I did.
I know that I am an alcoholic or a suffer of AUD, if you prefer, and you can make that informed decision on your own.
You make a compelling case that the answer should be affirmative, but that's your call.
As Dee said, we don't get into hair-splitting, but he (and I) have both enjoyed our clean and sober lives much, much more than in the days of drinking and/or using.
I don't think you found your way into SR because your drinking was going well - just a guess on my part.
We hope you stick around and that you decide you want to stop drinking.
As another poster has said, we do it one day at a time - we tackle sobriety in inches, not miles.
