Cognition Enhancer Research
oschobero writes to tell us the Economist has a look at pharmaceutical research as it applies to cognition enhancers. While the research is obviously focused on things like Alzheimer's, Parkinson's, and schizophrenia, the resulting drugs may also have a benefit to healthy minds. "Provigil and Ritalin really do enhance cognition in healthy people. Provigil, for example, adds the ability to remember an extra digit or so to an individual's working memory (most people can hold seven random digits in their memory, but have difficulty with eight). It also improves people's performance in tests of their ability to plan. Because of such positive effects on normal people, says the report, there is growing use of these drugs to stave off fatigue, help shift-workers, boost exam performance and aid recovery from the effects of long-distance flights."
I've taking Provigil. It's an amazing and weird drug.
On the one hand, It helps endlessly with functioning while sleepy. As a chronic insomniac, I'm never THAT awake, but after two hours of sleep and a provigil, I'm awake enough to drive and take exams. It doesn't even keep you up after it wears off, something every other sleep aid or wake aid I've ever taken does. It avoids the problem of body/mind disconnect, you're AWAKE, not brain awake/body tired or body awake/brain sleepy.
On the other, it has an effect I can only describe as "positional". You can still tell that you're tired, but you only feel it in one part of your head, kinda towards the lower-right-back area. And yes, that's insane.
What's weirder is that if you get a headache while on provigil, you'll feel it in that area too. It's kinda like it's turned off your brain's natural "error reporting" that tells you you're tired/headachey, but it doesn't do it for the whole brain.
I also had some nasty experiences in the bathroom while on it. That's definitely a downside. (Wee, rather than being late for class because I can't wake up I'm late for class because I'm stuck in the bathroom)
I only used it for about two weeks (despite the above praise, it didn't help with my main problem), but I'd definitely use it again if I had the chance. There's enough times where I've not gotten enough sleep for one reason or another but I really have to be at work the next day that it'd be quite handy to have around.
I respond to your sigs
I've used it before and it increased cognition considerably, especially when I was tired and figured I'd have a wasteful night of studying. If I have less than 8 hours sleep, I have difficulty focusing on a single source at one time, and studying is impossible. Ritalin has helped me micro-focus, and not just cram for exams but actually learn topics. If I had a steady source of Ritalin, or a doctor that 'played ball', I might consider experimenting with it more often.
Yup, won't be longer before passing a drug test for employment means your results have to come back positive.
Modafinil (provigil) is safer, more effective, and less addictive than caffeine.
Unfortunately, possession without a prescription can get you a year in jail. Strangly, it's chemical predecessor, Adrafinil is perfectly legal to buy over the counter (at about a tenth of the cost as well). It actually turns into modafinil in your stomach, but it takes longer to take effect, and the chemical byproducts cause stomach pains and liver problems.
Ritalin (methylphenidate), Provigil (aka Modafinil), Adderall (mixed amphetamine salts), etc are not the only options. In fact, there is a whole class of cognitive-enhancement drugs, called Nootropics.
The best of these (and arguable one of the safest), in my non-medical opinion, is Piracetam. It is a cyclic derivative of the neurotransmitter GABA, and has been used extensively since the 1960s in clinical studies, for treatment of Alzheimer's (and more), and off-label as a "supplement." Many studies suggest it increases blood flow (and hence oxygenation) to the brain, and protects the brain against damage from alcohol poisoning. It has no known LD-50, and has been clinically tested in daily doses exceeding 50 grams!
I personally use Piracetam to help study, and through my (obviously non-blinded and partially-biased) self-tests, I found that it really does help me learn things faster. After a cramming/studying session, I'll usually look back and realize how much material I've been able to learn in such a short time. All friends I've recommended it to have come to the same conclusion. My dosages vary from 1 gram up to 5 grams at a time, repeating every 3-4 hours.
Unfortunately, the reason why Nootropics aren't used much is because they don't have the intense effects that *stimulants* such as Ritalin do. The effects of Piracetam are very subtle (though the first time is more noticable)--enough so that its easy to get discouraged. However, when you take Ritalin, the stimulation effect is VERY noticeable (and fun, for many people).
The big problems with stimulants are that they aren't great for your body, they can encourage bad sleep habits, they are fun to use (possibly leading to irresponsible use), and they can lead to distraction for those not used to the effects at the used dosage. Additionally, they have terrible come-downs. A responsible stimulant user must recognize these aspects and make efforts to control them, otherwise they will not get any work done, or worse harm themselves!
Disclaimer: I'm not licensed to give medical advice. These are my opinions and are for informational purposes only. Using the mentioned stimulants without a prescription is stupidly illegal (but illegal nonetheless). I won't get into how prohibition is stupid and doesn't work (I think free-use regulation and accurate dispersion of information is the way to go). More importantly though, using these drugs improperly can be unsafe. Make sure you thoroughly research any drugs you use, including over-the-counter drugs, and consult a medical professional when unsure about possible interactions with other drugs or your health conditions.
