One day at a time, as cliché as that sounds...it really IS the best advice. (Not just in regards to drinking either)....
I find if I focus on "forever", it's too much. At least right now it is.
I can tell you (from my experience)...that with each day/weekend/holiday/function ...sober...it isn't so scary. You start to enjoy these things without the booze/regret/guilt/etc.
Your brain starts to realize that "hey! this isn't so bad at all...in fact, it's pretty freakin' awesome"
hang in there
