Welcome back Walter. I'm not young anymore either, and like you want to live last part of my life in sobriety.
You appear to have a terrific plan in place, and that's the way it works. "Just for today."
I will be 12 months sober in a couple of weeks and want you to know how much better it is than the misery of drinking no matter what life throws at me. My daughter has diabetes as a result of anti psychotic medication and can deal with her illness/s so much better now that I am sober.
Glad to see you back. I had to do same, and so very glad I did.
