Wow, I'm nearly three decades into life on Earth and I just this year started drinking alcohol, and only when I hang with friends. Guess it's my luck that I don't much like the taste...
I dunno how much time drinking actually could take in your days, but here's some suggestions you might find useful (I hope):
* begin a routine of sit-ups, push-ups, pull-ups (just do what you can and the amount will increase over time)
* climbing trees or urban structures
* plan attacks (and escapes from the scene) on all sort of institutions and property in any city
* nap on a park lawn or a beach
* visit a food bank for whatever you can use without cooking, see what you can put together from that
* collect cans or bottles to return for some recycling-deposit money, and think of other ways to make a buck
* take up a hobby of skill (a musical instrument, juggling, needlepoint, crochet, writing, drawing, painting, woodcarving, etc.)
* attend free movie showings, speakers, or debates/discussions at libraries, universities, and bookshops
* get a partner and fuck (be safe - and don't make babies!!!])
* stroll through a mall and notice how oblivious the workers and shoppers are to all the holes in security
* observe shoppers and try to estimate how much money gets turned into fuel for this rotten economy in exchange for unnecessary sweatshop-kid-made crap
* read books on C++ computer-programming, which you can practice and get a license to perform for big bucks (like a million other assholes)
* learn how to hack computers, so you can bring all of the industrial world to a sudden, grinding, crashing end
* go jogging, or play a bit of sport
* study some nutrition, so you know why drinking so much alcohol ain't so good
* kill and bury God
