Main Features and Dosage of Modafinil

Modafinil, as an active ingredient in various meds such as the brand-name Provigil & generics, is a med that fosters wakefulness. It’s primarily prescribed for therapy for narcolepsy, hypersomnia, obstructive sleep apnea (OSA), & shift work sleep disorder (SWSD). Physicians use modafinil off-label to treat other health conditions such as jet lag, ADHD, depression, chronic fatigue, etc. [1].

Dubbed the “smart drug,” it’s widely used off-label by healthy enthusiasts as a robust cognitive-augmenter med. Using it to boost brainpower, you achieve various cognitive benefits, including heightened focus, concentration, motivation, alertness, boosted short- & long-term memory, decision & planning skills, etc.

Modafinil comes as a tab (100 mg & 200 mg) to ingest by mouth. It’s typically taken once a day with/without food. If taking it to therapy narcolepsy or OSA, you’ll probably pop it in the morning. If using it to therapy SWSD, you will certainly take it an hour before the commencing of your work shift. This is similar to using it for cognitive purposes. For other conditions, take modafinil as prescribed by a physician.

Regarding dosage, 200 mg is the standard dosage. You can either increase the dosage to 400 mg max or lower it depending on your body’s reaction to med & tolerability. The prime thing to do is a microdose – starting at lower doses and increasing it until you reach the optimal dose strength you need.

The advantages of microdosing the “smart drug” generally are fewer minor negative effects, easier time falling asleep, & the capability to relax once the brainpower-demanding job is done.

Practically, you may pop a 50 mg modafinil in the morning. This offers solid cognitive augmenting effects for 5-7+ hours before the “half-life,” & usefulness seems to dwindle remarkably. You’ll be able to fall asleep around 13 hours after popping the 50 mg tab without any problem. This benefit is just 3-5 hours earlier for you than on a typical 200 mg dose. No negative effects. You’ll even be comfortable using this dosing 3 days in a row without experiencing any changes in cognitive benefits.

Using a 25 mg modafinil in the morning & 25 mg after lunch is indeed extremely unique and surprisingly useful. 25 mg “smart tab” with an espresso just gives you about 4 hours of intense focus & other cognitive benefits. Taking another 25 mg in the afternoon offers you another 4 hours of ideal brainpower effects. No minor negative effects whatsoever. Highly urged, as long as you’re not seeking to move mountains. Certainly, a 200 mg tab is ideal for “mountain moving.”

While standard 200 mg dosing practices put in 12+ hours of wakefulness & cognition, there’s no denying microdosing the “smart drug” works & could be most suitable when crushing 6-8+ hour days.

The minimal negative effects of microdosing “smart tab” & the capability to fall asleep at normal times are extremely ideal, along with the still remarkable cognitive augmentation & benefits.

The only thing to do so is to split the modafinil dose. By split dosing modafinil tab, you discover the effects are more stable & super predictable.

It’s typically cheaper to shop “smart drug” online in 200 mg pills & then cut them into two identical 100 mg doses — if that’s how you opt to take the “smart drug.”
