I think the whole premise that it should be hard to go 40 days without alcohol is ridiculous. If not drinking for 40 days is an experiment you're already in a minority with an unhealthy relationship with alcohol.
Changing your habits is hard and requires thought. I've recently given up meat and am suprised at the changes I've felt and at how difficult it is to socialize (restaurants, buffets, etc.) Does that mean I had an unhealthy relationship with chicken?
