It was November 2012 when Dennis Hartman, a Seattle business executive, managed to pull himself out of bed, force himself to shower for the first time in days and board a plane that would carry him across the country to a clinical trial at the National Institute of Mental Health (NIMH) in Bethesda.
After a lifetime of profound depression, 25 years of therapy and cycling through 18 antidepressants and mood stabilizers, Hartman, then 46, had settled on a date and a plan to end it all. The clinical trial would be his last attempt at salvation.
For 40 minutes, he sat in a hospital room as an IV drip delivered ketamine through his system. Several more hours passed before it occurred to him that all his thoughts of suicide had evaporated.
“My life will always be divided into the time before that first infusion and the time after,” Hartman says today. “That sense of suffering and pain draining away. I was bewildered by the absence of pain.”
