This was a big struggle for me at first. It used to be that I'd wake up on Saturday, knock out any chores, then go sit at the bar all day. I've found that my weekends are so much more interesting and full now, and feel so much longer.
For example, I'm off today and took a nice walk with my dog. We saw several cute cats then chatted with neighbors. Then I went shopping and got a new book, and they gave me a coupon for a coffee so I sat in their café and read for a while. Grabbed some food then charged my car. Got home and beat an absolutely amazing videogame (Spiritfarer) and it's only 2:30pm - I still have half a day to do whatever I want! I'll probably hang out with a buddy for a while, take another walk with the pup, maybe cook a nice dinner, and videochat with a crush (we have a date tomorrow).
It does take time and effort to get your mind out of the cycle of just doing things to get them done so you can go drink, but trust that life is so much more fulfilling once you get there.
