To do the Brandt-Daroff exercise:

• Start in an upright, seated position.
• Move into the lying position on one side with your nose pointed up at about a 45-degree angle.
• Remain in this position for about 30 seconds (or until the vertigo subsides, whichever is longer), then move back to the seated position.
• Repeat steps 2 and 3 on the other side.
