About
I'm Kate Black Swan.
I write about the psychology of alcohol, why quitting is harder than it should be, and what actually helped me. No motivational quotes — just everything I wish I knew when I first got sober. Seven plus years sober, author of One Day Sober, and creator of the One Day Sober app. Based in Switzerland.

The short version.
I spent years negotiating with myself like a hostage. Every morning: today is the day. This is it. Every evening: one more won't hurt. I meant both, every single time.
I didn't want to quit drinking. I wanted the consequences to stop.
The thing that finally shifted wasn't willpower. It wasn't hitting bottom. It was a change in how I thought about alcohol — what it was actually doing for me, what it wasn't, and what the story I'd been telling myself about it was really worth.
I've been sober for over seven years now. The book and the app are everything I wish someone had told me when I first tried to quit.
What this project is.
The book is a mindset-shift book about alcohol — not a recovery memoir or a self-help manual. The core argument: the reason most people can't get sober isn't willpower or timing. It's what we believe about alcohol, and about ourselves.
The app is a private tool for understanding your own patterns. Daily check-ins, pattern insights, and an offline urge-interruption flow.
The Journal is what the book and the app couldn't include — journaling prompts, practical exercises, and longer essays. No toxic positivity.
A note
I'm not a doctor or a therapist. This is one person's experience plus a lot of reading. If you've been drinking heavily every day and can't remember the last time you had none in your system, please talk to a doctor before stopping — alcohol withdrawal can be dangerous. See the full disclaimer.
