Hi DinaA and welcome to SR!
I don't know how qualified I am to give advice but what I can tell you is that I did EXACTLY the same as you for years. Drink every night until passed out and start as early as I possible could on weekends. It was what I did for so long I had absolutely zero confidence in my ability to get and stay sober. So I started "trying"....... read into that that I went from daily drinking to short periods of sobriety and massive binges in between. The addiction and its affect on my health progressed even faster during this period and I simply had to stop. For good. Total acceptance that this was forever.
Still early days for me (hopefully I'll hit 3 months next week) but with hand on heart I can tell you that YOU CAN DO THIS!!!!!!
Please lean on this site as much as you need to. I have literally been hand-held through difficult days from some wonderful people here.
Make that commitment and vow to yourself that you will get to bed sober tonight no matter what!!!!
I wish you all the best you won't regret this xxx
