For people juggling family, work, and a personal life, feeling exhausted may seem like it’s just par for the course. In fact, it’s estimated that 18 percent of adults suffer from feeling overly tired. While in many cases the condition can be remedied with a solid nap or a weekend of early bed times, when a lack of energy interferes with your productivity or causes forgetfulness or irritability regardless of how much you sleep, it’s time to talk to your doctor.
