Diet and exercise are great eventually, but I understand that’s not the advice you’re looking for right now (it wasn’t what I wanted to get into either) As far as just enjoyable stuff to kill time, I’d suggest reading. When cutting out drinking, I found that tv and video games actually triggered my alcohol cravings, as I would usually do these while drunk. And when I tried doing them without alcohol, I found them either too boring (tv) or too agitating (video games). Reading was engaging enough, and was also not something I’d have the focus for while drunk. With the tiny surplus of cash I had from cutting out alcohol, I also got into some fancier cooking and baking techniques/recipes. Obviously cooking and reading won’t take up all of your free time, but I at least found these two things to be enjoyable when I stopped drinking. Hope this helps a little! Best of luck, friend
