I've been drinking for a longer period of time, but really piled on the alcohol over the last 10 years. I can’t say when “the fog” lifted in sobriety, as it seems like things just gradually improved over time. Almost 2 years in, things are still getting better.
I’m 45, and one thing I acknowledge is that with age my body is changing. I'll never be the same as in my 30’s, drinking or not, so I work to support my body as much as I can through exercise and a healthy diet. But I will say that I’m a hell of a lot wiser now than then, so hopefully that offsets my ever-increasing “senior moments”.
