Sounds like you're doing everything right - well done!
All I can really add is to carry on with the good work ..... that said, here are a couple of things you might like -
I do Tai Chi, which is a martial art, but not as aggressive as things like karate or judo, it's more to do with balance, coordination, and stretching
There is also a mental/meditation/motivation aspect which keeps me on my diet and the straight & narrow; it just depends on how involved you want to go
There are loads of videos on YouTube - some simple, and others more advanced & complicated
I suspect that if you've given up smoking & drinking you might be saving money, and be well on the way to a lower weight or HbA1c target
So in the not too distant future you could think about a treat or reward such as a holiday, new clothes, a couple of expensive new kitchen knives, or whatever
