Congrats on your 60 days. Going on vacation is tough, but absolutely doable. Remember that many people ( most actuallly ) don't obsess over how many drinks the will or won't have prior to going somewhere - only Alcoholics do that.
I'm guessing you had a reason to stop drinking 60 days ago - are you suggesting that those reasons no longer exist? You know it won't be just one or two, that's just your addiction talking.
