Bob, welcome and you have plenty of support here.
It goes without saying here - Thank God no one was injured and you all got home safely.
Alcoholism is progressive and I found towards the end that I would pass out constantly, have massive anxiety and my body just didn't seem to handle it too well. Of course years of boozing will do that.
I focused purely on the day and sometimes hours at first. I made sobriety my focus and I got into recovery. There are many options out there for you so do some reading and find one that will work.
With recovery, I was able to kickstart a positive life in all aspects. I found it to be a journey and one I am working on each day. I no longer think of drinking or if I am in a bar or any place where alcohol is because I know now how much of a better person and how great my life is without it.
Keep sharing and looking forward to the journey.
