I'm also in the 70s since my final relapse-- Dad-well done.
I've also typically had a history of fairly "easy" quits compared to many.
What I had to learn to watch out for was the 3,6, 9, 12 month marks as
cycles where I'm tempted to think I can moderate.
As long as your clear you can never go there, you may find things roll
along quite happily
