Answer:
Often young college students come home from school overworked and overtired. You might consider sending your student to see his primary care physician for a check up. The physician will probably start by getting a good history of his nutrition, sleep and study schedules, and ask about his caffeine intake - which includes "energy" drinks that many young adults are using today - as well as asking about drug and/or alcohol use. Of course, this questioning is all confidential. Depending on the interview, the physician may consider lab work for anemia or a viral infection like mononucleosis.
