People with excessive daytime sleepiness brought on by narcolepsy, Obstructive Sleep Apnoea/Hypopnea Syndrome (OSAHS), or shift work sleep disorder (SWSD) are treated with Modvigil 200mg to help them stay awake. A sudden, uncontrollable tendency to fall asleep during typical awake hours is a symptom of narcolepsy. Even when it is incorrect or potentially dangerous to do so, this occurs at random times. This unwelcome excessive daytime sleepiness is reduced by Modafinil.
