I've been buying myself nice clothes with the booze money and generally making myself look presentable. I even go for haircuts nowadays! When drinking, having a haircut just cut into my drinking time so I'd walk about looking like Hair Bear for 6 months at a time. It's amazing how much better it makes me feel mentally knowing that I physically look ok!
I've also been spending money / time on maintaining my road bike, and buying myself some new video games.
