I’m 17 years without alcohol, 16 without “le drugs”, and 15 without smoking. I still have issues in my life and challenges to solve but wow, all of those would be harder and more numerous if I still behaved like I used to. I had a fairly short period of massive excess and had a few lucky moments of clarity which resulted in me quitting it all one after another. My partner and I have been together since just after I quit drinking and I am really glad they never had to see me being my worst self.
My biggest takeaway is it really does get easier with time. The hardest times were within a short time of quitting. The longer I sustained the more ingrained the change became and now I would be stubborn and resist any sort of backslide.
I can genuinely point to Jupiter, any time, day or night. I may need to get my bearings for NSEW but assuming I have any point of reference I can just point at Jupiter. It is my favourite planet and since I was a kid I was a little obsessed and figured it out, now it just runs in the background like a little JPS (Jupiter Positioning System) all the time.
