Hello Vickie28 and welcome.
Firstly,please allow me to offer my sympathies and regret for what your husband is currently diagnosed with.
Alcoholism,if left untreated,is a progressive disease and the saying in the rooms is that it can only take you to 3 places: jails,institutions and death.
The harsh reality is if he doesn't cease drinking,his life expectancy substantially decreases.
I know it must be difficult;seeing him in this state and unable to effectively improve his condition.
My prayers for at least a modicum of relief are on their way.
