Depending on your financial situation, you can do something fun or productive with the extra money you have every month. For me every time I quit drinking that’s the most dramatic change is that I just suddenly have four or 500 extra dollars in my bank account every month.

Do the math on how much you typically spent in a week or in a month on booze, and make a point to set that money aside: save it, donate it to an effective charity, buy yourself something nice with it. Celebrate that extra money every month in some way. Very motivating for me.
