Advice and suggestions: Stop drinking entirely. Work on the issues underlying why you turned to alcohol even when it was clear to you that it was not helping, but rather harming your agenda for life.
If you cannot stop drinking, entirely, on your own, get help. A support group (online or in real time) there is some pill you can take that makes you ill if you consume alcohol. Get rid of all the alcohol in your home. Tell your friends to NOT offer you booze. Change your route home from work so you don't pass the liquor store. Pay at the pump so you don't go in and buy a beer. Spend an evening here or in a support group meeting so you won't be home alone and tempted to booze up. Get a recovery pal to whom you stay accountable for not drinking. Those things can help.
There are many ways to work on the underlying issues. The first is to recognize they exist, identify some of them and tunnel through. Books, therapy, support groups, online sites etc can all help.
