Many drugs taken to relieve typical symptoms of motion sickness (including nausea, dizziness, etc.) contain compounds that may exacerbate drowsiness. Antihistamines are commonly used to treat motion sickness; however, side effects include drowsiness and impaired cognitive abilities. Anticholinergics such as scopolamine have also proved effective against motion sickness, but may induce drowsiness. These treatments may be combined with stimulants to counteract typical motion-induced nausea and dizziness while also preventing sedation. However, many stimulants possess addictive properties, which result in a high potential for substance abuse. Some stimulants also tend to interfere with normal sleep patterns. Modafinil has been studied as a possible treatment for the<unk>  that does not appear to have the same side effects of normal stimulants. Modafinil appears to be effective when taken in combination with anticholinergics such as scopolamine, but studies of Modafinil-only treatments for motion sickness remain inconclusive.
