I find you will pretty much get the same answer from most here.
You don't have a future. You have only a now.
With that in mind what are you going to do about now. And if you focuse on that with regard to drinking then nothing else matters.
Of course planning for tomorrow in other life area is essential. Just not drinking.
So plan that vacation. When it rolls around and you know how to handle now you will know what to do.
