You won’t regret this decision if you push trough.
First weeks are difficult but you can do it!
Get rid of alcohol in your house and fill your fridge with healthy food and drinks (and some chocolate too 
)
Maybe you wanna check this thread out:What's YOUR plan? It give loads of information about quiting and the proces.
If you are a bit like me maybe you wanna read recovery books ore listen to some podcast about recovery? I used it as a distraction too to go for a walk in nature when I had cravings and listened to a podcast about sobriaty. Here on this thread you will find all kind of books and podcasts worth mentioning: Resources for our recovery And if you wanna join online meetings somewhere you will find the links to them there too.
If you have any questions, feel free to ask!
And WELCOME here ofcourse, it’s a good place to be despite the circumstances.
