So how much Modafinil should you be taking in a day to derive the greatest level of positive effects? Modafinil is typically sold in 100 mg or 200 mg tablets with the 200 mg option being more popular and more widely available. The typical recommended dose is 200 mg, taken once per day, usually during the morning. It may be taken with or without food.

Some individuals recommend starting with a 100 mg Modafinil dosage for your first week so that you can become accustomed to the effects. It is also possible to take higher doses. Up to 400 mg per day has been shown to be very well-tolerated. However, it is also unclear as to whether or not increasing the dose will have any additional positive benefits. This is a determination that can best be made after consulting the advice of a qualified doctor or health care professional.

Using Modafinil is quite straightforward. For starters, it is considered to be very safe and generally well-tolerated. This is especially true in otherwise healthy people.

If you are using this supplement as a method to fight off shift work sleep disorder (i.e. excessive sleepiness when working, due to irregular schedule or hours), then consider taking the supplement one hour or so before work starts. Most user reviews say that it is almost impossible to fall asleep within 12 hours of taking this drug, so plan accordingly for when to take your dosages. There are some who believe Modafinil should be dosed based on body weight, however there is little evidence to show that this is necessary for the average user.

Despite the fact that this drug is viewed as quite safe, there have been a few side effects associated with its use. These include headache, nausea, nervousness, rhinitis, diarrhea, back pain, anxiety, insomnia, and dizziness. In placebo-controlled studies, 8% (versus 3% of those who received the placebo) discontinued use due to an adverse reaction or side effect(s). Of these, headache was the most frequently cited reason. Generally, using the appropriate Modafinil dosage will not lead to side effects and dangerous reactions are extremely rare.
