Modafinil is a mild stimulant typically prescribed for sleep-work disorder. It is effective at promoting wakefulness without the side effects that typically accompany stimulants.
- Keeps you alert and awake for hours 
- Increases concentration and attentiveness 
- Mood booster, helpful for treatment of depression 
- Treats bipolar disorder, cocaine dependence, parkinson’s disease, and schizophrenia 
- Cognitive enhancer, improves working memory and pattern recognition 
- Weight loss effects, reduces appetite 
What Is Modafinil?
Modafinil originated in the late 1970’s. It is currently approved by the US Food and Drug Administration for the treatment of narcolepsy, shift work disorder, and excessive daytime sleepiness. In Europe it is prescribed for narcolepsy. At first modafinil was shown to be an effective treatment of ADHD. The FDA eventually repealed its prescription for this use in 2006 because they felt it was unsafe for children. In the United States modafinil is classified as a Schedule IV controlled substance under federal law. However, it is not controlled in Canada, Mexico, the UK, Australia, Germany, and India. It is available for purchase online with no prescription.
The United States military has approved Modafinil for certain Air Force missions in order to keep pilots alert and maintain their accuracy for up to 40 hours without sleep.  A report in the Canadian Medical Association Journal stated that Modafinil is used by astronauts on long-term missions aboard the International Space Station. Because many astronauts suffer a reduced quality of sleep Modafinil was taken by the astronauts to stay attentive and accurate. 
Modafinil Dosage Information
Modafinil usually comes in either 100mg or 200mg tablets. It is generally taken one time per day with or without food. Do not take large doses, do not take it more than once per day, and avoid taking it for extended periods of time. It is potentially habit forming.
How Does Modafinil Work?
Even though the precise mechanism of action of Modafinil is unclear there have been many studies which have produced theories. The most recent study suggests Modafinil affects the dopamine transporter, inhibiting the reuptake of dopamine. This means that dopamine is released but is not reabsorbed leading to much greater dopamine levels.  This produces a state in which a person is abnormally active.
Safety and Side Effects of Modafinil
Modafinil is a serious nootropic and you should consult your physician before use. There is a long list of special precautions and side effects that can be viewed here.
Where Can I Buy Modafinil?
Modafinil is a scheduled substance in the United States and can only be legally obtained with a prescription. If you live in the Unites States consult your physician and obtain a prescription if you believe you have a use for Modafinil. In most other areas Modafinil can be purchased online without a prescription.
It is closely related to Adrafinil, however, which is available over the counter in the US.

Other studies have shown that Modafinil decreases food intake by laboratory animals and humans. Though the study was aimed to determine if oral doses of Modafinil helped day-shift and night-shift workers stay attentive and awake, reduction in caloric intake was observed as well. The study showed that 200mg/day doses decreased caloric intake by 18% and that 400mg/day doses decrease caloric intake by 38% regardless of which shift the workers were on. Tolerance to these anorexic effects was not observed. The end conclusion was that Modafinil produces a clear reduction in food intake and that future studies should be aimed directly towards this effect on obese patients.
