Hey there!
Well done on 23 days! Can you imagine saying that to yourself 4 weeks ago when you were in the midst of the chaos of thinking about drinking, buying drinks, planning drinking, actually drinking, recovering from drinking, like you say it was all consuiming. I feel exactly the same. Day 38 for me, hard to really believe it...
I would recommend taking up some new hobbies, however small and futile they might seem. I paint pebbles, I collect them from the beach, paint them with acrylic paint, design something or write something on them with permanent markers and then varnish them. It's quick but very satisfying!
I also volunteer for a few different groups which when I was drinking was hard to keep up with, I used to go to meetings but clock watch until I could go home and drink again. Or I used to promise to be somewhere in the morning, knowing what challenge that would be, and then turn up hungover as hell. Now I'm relishing the fact that I'm clear headed, present and sober, it feels so nice to be able to RELY on MYSELF again : ))))
Try and fill your time so you don't have that void : )
