You’ve done it mirrorball. You’ve ended your addiction without ever giving up your personal responsibility for using and for quitting; without ever giving up your knowing you could do it by yourself.
As to your not looking forward to a boring month, I believe there is no such thing as “boredom” for people outside of solitary prison confinement. It’s your Beast that is now in solitary prison confinement.
YOU, on the other hand, are now positioned for all kinds of experiences with the huge variety of profound and subtle human thoughts and feelings that go with it. I’ve found life MUCH more nuanced and interesting as a teetotaler than it was getting that same old whammy of chemically enhanced whatever-you-want-to-call-it.
Your Beast will be continuing to make you feel doubt about staying quit. Your Big Plan (with whatever jewelry and rituals you might enjoy to honor it) is the guarantee of your permanent abstinence.
