Who it's forA man who has to perform after a short night: a new baby, a deadline, travel.

When to see a doctor
  • Falling asleep or fighting sleep while driving: do not drive until a doctor has the sleepiness under control.
  • Loud snoring, breathing that stops and starts in your sleep, gasping or choking noises, or always feeling very tired in the day despite long sleep: see a doctor, for sleep apnea.
  • Tired for a few weeks with no clear reason, tiredness that affects your daily life, or tired with weight loss or mood changes: see a doctor.
