Wittss, welcome to SR.
I have a 32 year old AD who already has COPD, and is morbidly obese. Although she is not currently drinking, she's switched the addiction to prescription meds like Xanax.
I have no personal experience in living with an active A long-term, other than my EXAH, and I finally hit a bottom with him and had to walk away for my own sanity/safety.
He was buried a few years ago at the age of 47.
I know others will be along to share their experiences.
I just wanted to welcome you, and let you know you are among friends.
