No-buy month actually for me worked pretty good when I want to curtail my drinking back several years ago. Instead of deciding not to drink, I chose not to buy, so if I went to a friends house and that friend offered me a beer I did not feel bad or strange in anyway in accepting the beer, because I was not quitting drinking, I just quit buying beer for that month.

It is a shame I could not do the same with smoking back then, far to much of an ingrained habit for me.
