Hey there’s also intherooms.com they have meetings in all programs, 24/7.
My advice to you is don’t rely on some shot to help with cravings but sort your alcoholism out yourself. You grew it, you can understand it and you can live a sober life if you do it right. Engage with yourself, build strong new routines, work on the reasons why you drank, build a new life that doesn’t make you want to check out of it.
