I went into detox for a week in 2017, and I've just hit 2 years sober and even now I'm not adjusted to life without it yet-you just have to "wing it" and accept that your job and personal situation can an WILL only get better.......i was known as the clever drunk where I live-the word alcoholic tends to drown out the clever bit.......get a hobby and that's not a joke.
I've spent 2 years learning the ins and outs of apple stuff because MS just bores me now-and after that-i bought a 3d printer kit in a box off amazon-you have NO idea how many hours i've spent on this-I know it sounds far-fetched but try to break the routine or mould........and it's rewarding as well because you're doing something you didn't think possible-dopamine release makes you happier anyway but it's still a "look what i've done" thing-gives you a bit of pride.
Hope it helps someone, if not you.
