I agree with the others. Go easy on yourself. Get support if you’re feeling like you can’t do it (because you can). Also, after a long time drinking heavy, perhaps you may need medical support (just a thought).
You’ll soon feel better and then you’ll need to focus on a plan to keep you sober. With so many online here you’ll come up with a lot of ideas.
I wish you the best and look forward to hearing about your success!
