That was the first thing I thought. You could also make instruments. If you don’t want to sink a lot of money into it, you could make cigar box guitars.

Drink other stuff? Learn to distinguish whiskey from bourbon from scotch. Ouzo from Raki from saki. Single malts from, er, multiple malts? Oh, whatever, seems like I’m the one who needs lessons in all this stuff,
Post-90s web design.
Take some crafts classes? If you don’t know what you like to do, and you don’t have anything in particular you want to make, you’ll just be aimlessly experimenting and you may be frustrated or bored.
If you find something you really would like to work on because you enjoy the results (gardening, cooking, sewing, knitting and woodworking seem to be solid performers here, but there are lots of other ways to make things as well), then you’ll be invested in it and will enjoy it, and will get lots of positive feedback when you make things for other people as well.
Congrats on being sober(er), it really is fun when you get used to it!
How about getting another job or doing voluntary work? Live TV is basically all crap 90% of the time and requires copious amounts of alcohol and/or drugs (or stupidity) to make it bearable, all that pent up energy could be put to really good use.
Thank you for recommending my book. You can see all my art work at www.salvillano.com
Your work is seriously gorgeous!
JustinC mentioned volunteer work, and you might know this already but there are things you can do from home, not tied to specific hours. For example, I’ve made calls for the Humane Society to remind people about an upcoming event, or thank them for a donation. Another type of service is to pick up a bunch of cards that need to be sent out, then personalize them as requested and drop them in the mail. Or you can do projects based on whatever expertise you have. You could contact the volunteer coordinator of an organization to discuss possibilities if this interests you.
USCDiver mentioned adult coloring books. I got some of those at Christmas, and I really like it. It can be as simple as filling in color between the lines on the page, or getting more creative with it with different materials and techniques. There are lots of YouTube videos on adult coloring and/or drawing, if this interests you.
Do you ever go on Pinterest? That might be a good place to browse for artsy crafty ideas.
Painting?
Hiking and walking?
Bicycling?
Museums big and little?
Photography?
Zentangle, creative doodling. You don’t have to be artistically inclined. Amazon has a number of books, and my favorite is One Zentangle a Day. It’s helped me get used to sobriety.
If you want to do something a little more ‘presentation’ worthy beyond just knitting and spinnin’ yarn, you could try macrame (knots instead of weaves). It’s not too tough once you dive in and you can actually use it to hang stuff. You can hang it off the wall also, as its own slice of art. Here’s a little intro to it. Try the small stuff and maybe sketch/ macrame something for your kitchen or bathroom 
You could also try cross stitch as it used to suck me in for hours. You could also try learning a New and Useless Skill every year, as in something you wouldn’t put on a CV. So far I’ve tried Blues harmonica, Tin whistle, knots, origami, and the minimum math to do QM and Theoretical physics. Anything at all that interests you.

Jewelry making is fun. I made a bunch of paper beads and strung them into long strings and made a bead curtain. Cheap and time consuming and EASY. You need old mags and plain old glue. Don’t buy the kit, it is worthless get a toothpick or skewer to roll with. Plenty of instructions on Pinterest.

Hey you asked, us boring non drinkers have a life to fill up, too! Seriously if you were honest the ammt. You were drinking doesn’t sound excessive, to me! Could be I am wrong though, I have been around heavy drinkers my whole life. So judge for yourself, IANP.
To be honest, I usually drink while doing all those activities I mentioned.
I think that the embarrassed face might be related to the fact that this thread was a year and a half old when Rick Vallejo bumped it. Grrr!'s situation has probably changed significantly in that time, in some way, that makes this thread less relevant (possibly including having returned to drinking, having found a satisfactory new hobby already, or having learned to cope with sobriety without a new hobby).
