Hello Izz
I am walking alongside you in this journey. My AH is detoxing. Has been safe so far. I did a detox at home on my own too when I quit drinking about 10 years ago. I was fine.
With my AH I am there for him but also very much staying on my own side of the street. Maintaining my own recovery program.
My feeling is that it is vital to have follow up help to maintain the quit.
In my AH's case he has a team of addiction support workers to help him.
Without a program of some sort, it is far harder to stay quit and also to do the work needed to build a good life and find coping techniques other than drinking.
All the best to you.
