You can relieve drowsiness by treating the cause of the problem. First, determine whether your fatigue is due to depression, anxiety, boredom, or stress. If you are not sure, talk with your health care provider.

For drowsiness due to medications, talk to your health care provider about switching or stopping your medications. DO NOT CHANGE MEDICATIONS WITHOUT FIRST TALKING TO YOUR HEALTH CARE PROVIDER.

Your health care provider can treat hypothyroidism, hypercalcemia, and hypo/hypernatremia.

For drowsiness due to narcolepsy, your doctor may prescribe stimulants (such as Ritalin).

For drowsiness due to other causes, seek medical help.

Contact your health care provider if you think the cause of your drowsiness is from any of the above conditions.

The doctor will examine you to determine the cause of your drowsiness. The doctor will investigate your sleep patterns, and you'll have a psychological profile taken.

  • How much do you sleep?
  • Do you snore?
  • Do you have episodes in which you do not breathe during sleep (sleep apnea)?
  • Do you fall asleep during the day when you are not intending to nap (such as when watching TV or reading)?
    • If so, do you awake feeling refreshed?
    • How often does this happen?
• Emotional state
  • Are you depressed?
  • Are you anxious or feeling stressed?
  • Are you bored?
• Other
  • What medications do you take?
  • What have you done to try to relieve the drowsiness?
