Welcome Livestronger!! I too like you was in jeopardy of ruining my marriage because of alcohol. I also was drinking while on an SSRI. I did this for 5 years, and was actually gasping for air when passed out due to the affects on the nervous system. Again like you, I slowing was drinking on the weeknights and at the end it daily. Alcohol was a huge part of my social circle, but it really does get easier to hang out with friends sober.
I'll have one year of sobriety next month and I never thought in a million years I could obtain even a week without a drink. You can do this if you want, it isn't easy some days, but it's well worth it in the end. I use SR as my main tool for staying sober, I actually look forward to reading/learning about my addiction. You will resonate with a lot of people on here and even though I have never met any of these nice folks I feel like they are my friends. Good Luck and I hope you stay sober for yourself and yor family!!
