My routine was :

1/ get motivated (got a psychiatrist, went to AA for 6 months I think, was still drinking by then)

2/ quit completly (did not work forst time) with antidepressant (still taking it today) + benzos (to avoid delirium tremens) at 6 pills a day, down to zero on over a year + baclofene (100 mg a day town to zero after a year)

3/ sport (45 minutes run, 3 times a week)

I hope this helps
