with David Millar

David Millar is a medical student and ultrarunner who rebuilt his life after addiction to alcohol, cocaine and crack.

“I treat it like a pill a lot of the time.”
David Millar

Summary

Millar describes growing up in Ocean City, New Jersey, where he watched addiction and assumed he would avoid it. His first drink came as a teenager; by sixteen he was using cocaine, and the drive to keep going led to crack, leaving college, repeated treatment stays and nights sleeping in the woods. He recounts stealing to fund drug use, fleeing detox and cycling through psychiatric wards.

At twenty, meeting people who embraced recovery made a sober future feel possible. A year in a structured Los Angeles program taught him daily discipline and accountability. Millar returned to school, finished a psychology degree, worked in a hospital and took the MCAT before entering medical school. He talks about keeping recovery private in his application, running as a stabilizing practice, and channeling the same obsessive drive that once fueled addiction into study, coaching and endurance races.

Show notes

David Millar grew up at the Jersey Shore surrounded by addiction, promising himself he would never become like the people he watched struggle around him.

Instead, by age 20, he was deep into alcohol, cocaine, and crack addiction. He dropped out of college, cycled through psych wards, detox centers, and rehabs, slept in the woods, stole to survive, and believed drugs would define the rest of his life.

Then everything changed.

David got sober, rebuilt his life one day at a time, rediscovered running, returned to school, and eventually earned acceptance into medical school despite being told his past would hold him back.

Today, he is seven years sober, an ultrarunner, medical student, coach, and one of the most powerful voices in recovery.

In this conversation, David shares the reality of addiction, life inside psych wards, sleeping in the woods, the treatment program that saved him, why running became his medicine, and how he transformed an addictive personality into a force for growth.

This is a conversation about addiction, recovery, discipline, and what becomes possible when you refuse to quit.

You got You got to learn to tame yourself and kind of be in control rather than just letting it spill.

Key takeaways

  • Early sobriety felt uncertain because Millar had never learned how to live without numbing himself.
  • Daily structure and accountability helped him practice habits he had resisted before.
  • He learned to direct obsessive energy toward work that can serve other people.
  • Running gave him a repeatable way to manage stress and build confidence.
  • Sharing a recovery story can give younger people a picture of sobriety in their twenties.
