I quit almost exactly 2 years ago. Parties are not as fun anymore. Do not take all that “you can party without alcohol” BS at face value unless you actually try to – unless you’re a highly sociable person to begin with of course (I for one am not).
Every once in a while you will get this craving, this urge to get wasted, or just have a beer or a whiskey, or an irish coffee. You will start thinking you might have been an alcoholic because of that. Not necessarily, smokers from what I hear also suffer from this kind of “post partum” e.g. dreaming of drinking / smoking. Heck I had nightmares, after turning vegetarian, of me eating meat and then realizing I wasn’t supposed to – crazy stuff.
My point is, I suppose, you don’t need a ‘strong motivation’ to quit, because that’s not enough. You need certainty, that not drinking alcohol is paramount to you being the person you want you to be, otherwise you won’t last 2 months.
Trust the sober-atheist-vegetarian jelly (who’s yet to kick their internet habit) on this one ;-)
Anyway: Good luck!
