Welcome!
It can take a year or more for the brain to recover from all the toxicity it was exposed to, chemically speaking.
What you are currently feeling, tired and board. Totally normal! Welcome to the club. It'll get better.
I would suggest finding something else to do with your time.
Do something with the kids, even if you are tired.
Definitely, work out, something physical, eat well to give you better healthy energy.
Read, go to a meeting, start a new hobby, knitting, painting, walking, there are so many things I believe we as alcoholics never did because we were too busy drinking.
I know I rather be too busy living than sitting on my butt drinking.
Best of luck, remember acceptance is key !
I bet you will fin d a lot of good information and support here.
