Wow thanks for your post, I too made 4 weeks yesterday a 1st for me in over 10 years for alcohol and weed daily before that for even longer. Also functioning pretty well mostly..
Anyway I too was waiting for the euphoria or something and today I think I had a glimpse, in work 2 things happened. One - I suddenly felt very sharp & present in a moment & I absolutely attributed that to not drinking. Secondly a realisation- I realised in need to make more changes on my days off to my lifestyle .. but that's another thing. Anyway congrats to you & me !!! (Even if I'm congratulating myself ha!)
