Welcome here and I hope your first weekend is going well!
While I doubt that the underlying reason for your addiction is actually boredom, this:
Is very wise. I built a very steady daily and weekly routine and tracked my habits for a long time in early sobriety and it helped me so much. Eventually I was able to participate in life again a bit more so outiside things took up more time, but my core habits and routines still keep me firmly grounded so that when shit starts spinning, which it does, I don’t fly off as far.
Routines are a hugely important tool. And while you don’t have anything to fulfill your soul and heart, if you’re used to boredom-drink, they can tide you over these times and tough spots until you develop (sober) passion(s) again.
Best of luck!
