Keep a drinking diary

It’s also a good idea to document and count alcohol drinks like you do kilojoules, Valentine suggests. “You can count the number of drinks and their size and this creates a consciousness.” Tracking how much you drink will provide you with some surprising information that will encourage you to cut down or quit.
Decide why you want to cut down on drinking

Make a list of reasons why you want to cut back on drinking. This could be: lose weight, sleep better, fewer headaches, get more done, improve blood sugar control, have better sex, perform better at work, says Valentine. Post the list in a prominent place and read through it every time you think about having a drink.
Make a money log

Track how much money you’re spending on alcohol every week, Valentine suggests. Now commit to spending half that amount. Put the savings into a special account (or even a jelly jar) and use it for something special for you (not a bottle of 2000 Bordeaux).
