Mark O'Sullivan has been sober for over 35 years. Drawing from his own journey of recovery, he writes with honesty, humor, and hope about life without alcohol. A former fire protection service manager and now a driving instructor, Mark has worked in many trades and seen firsthand the struggles people face in working-class communities. When he isn't writing, Mark enjoys spending time with family, visiting Ireland, and helping others on their own recovery paths. Staying Sober: What 35 Years Without a Drink Has Taught Me is his first book, written to inspire anyone who feels trapped in the cycle of drinking and searching for a way out.
