obstructive sleep apnea/hypopnea syndrome
"Provigil has saved my life, as the saying goes. I am taking 300 mg and 100 mg six hours later.

Despite my use of a CPAP and caffeine I still suffer from chronic fatigue and the Provigil has helped me to maintain some semblance of a normal existence. There are no apparent side effects and the result is to make me feel and act normal versus the side effects of other stimulants such as caffeine."
