The further you get from your last drink the more other things will fill the void that you're feeling right now. For my first month I felt very empty like you described. I've noticed that slowly other things have started to take up my time. Just remember that in the beginning it's going to be hard but does get easier. You need not worry about "what" might happen in 20 years. If you worry about right now... this minute... rinse and repeat... everything will work out well for you. Take care!
