Daniel Cage, a junior defensive linemen at Notre Dame, has had success on and off the field following the treatment and diagnosis of his sleep apnea, reports the Chicago Tribune.

The ABCs of Z’s wasn’t part of Daniel Cage’s planned curriculum at Notre Dame.

But the 6-foot-1, 310-pound junior defensive lineman was tired of being tired. Contorting his massive frame onto a twin bed at school wasn’t helping either.

So Cage, who said he has suffered from sleep apnea since high school, approached the team’s trainers during the spring and explained why he struggled to make it through practice, why he was running on Dunkin’ to stay awake during class.

A visit to a sleep specialist ensued, followed by a prescription of a CPAP machine that helps Cage breathe at night.
