Welcome Granpa,
I'll be 70 next month, I wish I had stopped the boozing when I was 60. Good luck on stopping, I'm at 29 days and had abused alcohol about 45 years with a 5 year break about twenty years ago. I retired in Jan and any time of day or night was the deal, usually fell asleep (passed out) for a few hours. Just getting the sleep better under control.
Hang in there, I'm rooting for you!
