Weight loss Studies on modafinil (even those on healthy weight individuals) indicate that it has an appetite reducing/weight loss effect.[56][67][68][69][70] All studies on modafinil in the Medline database that are for one month or longer which report weight changes find that modafinil users experience weight loss compared to placebo.[71] In 2008, one small-scale study on individuals performing simulated shift work quantified the effect as a 18% decrease in total caloric intake on 200 mg/day, and a 38% decrease on 400 mg/day.[72] However, the prescribing information for Provigil notes that "There were no clinically significant differences in body weight change in patients treated with PROVIGIL compared to placebo-treated patients in the placebo-controlled clinical trials." [73] In experimental studies, the appetite reducing effect of modafinil appears to be similar to that of amphetamines, but, unlike amphetamines, the dose of modafinil that is effective at decreasing food intake does not significantly increase heart rate. Also, an article published in the Annals of Clinical Psychiatry, presented the case of a 280 pound patient (BMI=35.52) who lost 40 pounds over the course of a year on Modafinil (to 30.44 BMI). After three years, his weight stabilized at a 50 pound weight loss (29.59 BMI). The authors conclude that placebo controlled studies should be conducted on using Modafinil as a weight loss agent.[67] Conversely, a US patent (#6,455,588) on using modafinil as an appetite stimulating agent has been filed by Cephalon in 2000.

Can anyone comment on it's efficacy as a weight loss drug? Wikipedia says it's subject to customs in Canada, is that dangerous for the buyer?
