Modafinil is sold in 200 miligram pills, however many users find that 100 miligram is enough to get the desired effects. You may want to try taking 100 miligrams the first time and scale up if necessary. Doses over 200 miligrams generally aren't recommended or necessary. Modafinil should not be taken more than once per day so users can sleep normally. Visit https://www.modup.net/ now to learn more.
