Though they’re related substances that produce virtually the same effects, they’re also different in some important ways.Here’s a comparison that may help you decide which one is right for you.Adrafinil and modafinil are both considered eugeroics, or wakefulness-promoting agents, that work by promoting long-lasting mental arousal.This sets them apart from traditional stimulants such as caffeine or amphetamines, which promote wakefulness by increasing overall physiological or nervous activity throughout the body.Eugeroics are a relatively new class of drugs, developed in the 1970s as a treatment for narcolepsy and other sleeping disorders. I have 60mg of Vyvanse and take it occasionally but now it is actually slowing me down, and I will stay on one stupid task for way too long and 4 hours go by.I want to try something new. People have reported blacking out after only minor amounts of alcohol while taking modafinil, and some people who have only taken one dose of Adderall mixed with one drink have ended up in hospital.Both modafinil and Adderall can affect the heart and blood pressure and mixing them with alcohol increases the potential of arrhythmias and other heart complaints.Several small trials have tried to determine if Modafinil really does enhance cognition, with mixed results. Here’s a comparison that may help you decide which one is right for you. This eliminates much of the agitation and euphoria associated with amphetamines, as well as the rebound exhaustion and “crash” typical of stimulant-produced sleep deprivation.The brain-specific mechanisms of action that enable eugeroics to promote alertness also make them exceptionally effective cognitive enhancers.They have become very popular smart drugs, widely used off-label by students, shift workers, and others interested in extending wakefulness and energy while performing at peak cognitive levels.Extensive research has confirmed that both adrafinil and modafinil have powerful nootropic capabilities, Eugeroics are invaluable for the treatment of sleep disorders like narcolepsy, obstructive sleep apnea, and shift work syndrome because they can effectively prevent excessive daytime sleepiness without giving rise to hyperactivity or interfering with regular sleep patterns.Both adrafinil and modafinil typically create less nervousness and anxiety than other stimulants, and research indicates they present only a very limited risk for the tolerance and addiction that is characteristic of the long-term or off-label use of traditional stimulants.The side effects of adrafinil and modafinil that are most commonly reported include anxiety, insomnia, headache, indigestion, and dry mouth. NewlyOCD's report was particularly noteable: Look at me, I think I'm interesting enough for an AMA! I personally don’t take Ritalin because it the effect it has on me is like I’ve just taken “stupid pill” that impacts my memory recall. If Adderall is suddenly stopped, it may cause a withdrawal syndrome (symptoms include extreme tiredness, depression, and sleep disturbances).Neither modafinil nor Adderall should be mixed with alcohol. However, there are very few trials investigating whether Adderall does enhance cognition in individuals without ADHD. They are both approved to treat ADHD (attention deficit hyperactivity disorder).. Vyvanse is not approved for use for children under the age of 6. Traditional stimulants like amphetamines boost dopamine levels by directly stimulating increased dopamine release, but eugeroics increase dopamine availability by blocking the neural receptors that remove dopamine from the system. The price of modafinil can be a real burden for prescription buyers unless insurance covers at least part of the cost, and it could be prohibitive for users who are interested in the nootropic benefits of eugeroics rather than the treatment of a sleep disorder.Adrafinil is available in a wide range of dosages at a fraction of the cost of modafinil.While both adrafinil and modafinil are safe, effective, well tolerated, and virtually identical in many ways, adrafinil is the right option for users seeking nootropic benefits because it’s readily available as a nootropic or dietary supplement and can be legally purchased without a prescription at a fraction of the cost of modafinil.Though adrafinil could potentially have some toxicity implications that modafinil doesn’t have, those are related to long-term use at very high dosages and have not been observed when adrafinil is taken at recommended doses for short periods of time.If you’re interested in nootropics that can temporarily banish tiredness and keep you at maximum energy and cognitive ability for hours without disrupting your normal sleep cycle or setting you up for a rebound crash, adrafinil is a nootropic worth considering.Join our Newsletter and get a free copy of our ebook The Encyclopedia of Nootropics.Thank you for signing up.
