Hi There , You and him already know this but
that,s a lot of alcohol and will be doing a fair amount of damage whether he is managing work or not . Its great that hubby wants to quit and my advice is to go for total abstinence with the help of his doctor should he suffer withdrawals .
Very few alcoholics are able to sustain a long drawn out taper and almost every time go back to square one . For me making the decision to quit over 6 months ago was the best decision I ever made .
I know from past experience other members on here you will offer similar replies regarding your hubby's slow reduction method .
I wish you well
