Welcome! You came to the right place for inspiration and support.
Congratulations for taking this huge step of admitting your relationship with alcohol is problematic and deciding to take control of your life.
It took me over a decade to come to this realisation I always created excuses not to stop.
I can promise you stoping is the best decision you will ever make. Living sober is living according to your true self and it is so liberating.
In the beginning of your journey I suggest to keep yourself busy - exercise (walking, bike, peloton, hitt, yoga), read or listen to podcasts and audiobooks about topics you are interested, watch movies, cook (try if even if you are not very good - I am not very good but I enjoy the process), meditate, organise your closet and hour home (sell or donate what you don’t wear - this will clear out the stagnant energy and feels amazing), volunteer/ mentor someone, learn something you always wanted - instrument, language, new skill (like drawing or calligraphy
Don’t socialise where people will be drinking in the beginning (I was only comfortable to do that after a few months)
In early sobriety I had a policy to say yes to trying everything that would add value to my life and would make me busy so I would not think about drinking - so I tried philosophy lectures (at the time face to face), guided meditation classes, kirtan yoga chanting classes (so cathartic), new moon rituals, various (!!!) exercise classes.
Some of those things became integral part of my life and routine!
Surrender yourself to this journey! Sobriety is transformative in the most amazing way!
I hope this helps
