Provigil and Caffeine
There were 50 healthy young adults who remained awake for 54.5 h (06:30 day 1 to 13:00 day 3). A 10-min vigilance test was administered bi-hourly from 08:00 day 1 until 22:00 day 2. At 23:55 day 2 (after 41.5 h awake), double-blind administration of one of five drug doses (placebo; Provigil 100, 200, or 400 mg; or caffeine 600 mg; n = 10 per group) was followed by hourly testing from 00:00 through 12:00 day 3. Response speed (reciprocal of reaction time) across the 10-min task (by 1-min block) was analyzed prior to and after drug administration.
A fatigue effect (response speed degradation across the 10-min task) was exacerbated by sleep deprivation and circadian rhythmicity. Prior to the drug, this effect was maximal between 08:00 and 12:00 day 3 (24-28 h sleep deprivation).
Provigil Generic and Depression

Narcolepsy. Symptoms.
Narcolepsy is a chronic neurologic disorder characterized by excessive daytime sleepiness and cataplexy and less often by hypnagogic hallucinations and sleep paralysis.
While patients report excessive daytime sleepiness and cataplexy as the more frequent symptoms of this condition, excessive daytime sleepiness is generally believed to be the most debilitating.
Narcolepsy often is undiagnosed or misdiagnosed for a variety of reasons. Although confirmation of an initial diagnosis requires monitoring of physiologic variables conducted at a sleep center by specialists, the primary care physician has a critical role in the identification and management of this incurable affliction.
Provigil for sustaining the alertness
The principal objective of this study was to determine whether prophylactic doses of Provigil would attenuate decrements in aviator performance and arousal throughout 2 days and 1 night without sleep.
Six pilots were exposed to two 40-h periods of continuous wakefulness. In one, three 200-mg doses of Provigil were given and in the other, matching placebos were administered. Helicopter simulator flights, resting EEGs, and Profile of Mood States (POMS) questionnaires were evaluated. RESULTS: Provigil attenuated sleep deprivation effects on four of six flight maneuvers, reduced slow-wave EEG activity, and lessened self-reported problems with mood and alertness in comparison to placebo.
The most noticeable benefits occurred between 0330 and 1130 hours, when the combined impact of sleep loss and the circadian trough was most severe.
