A quick Google, probably just as addictive as coffee, working on same pathway. I know idiots that drink coffee all day. If 2 cups of coffee don't wake you, 3 isn't going to help. Sleep is only time blood brain barrier opens up, letting lymphatic system to wash out brain neuron mitochondria metabolic waste materials. All the stimulants in the world won't remove them. Coffee has 5.5 ish hour half life, so 3 cups in morning leaves half cup worth of caffeine by bedtime, that cleaves to the adenosine receptors, inhibiting sleep, even if brain is begging for a sleep cleanse. Fortunately, or not, regular caffeine means brain grows more adenosine receptors, increasing need for more caffeine. So, the more caffeine you use, the less the drug works. Nothing is for free.... Stimulants will never reduce sleep required (by much, when averaged over a week or month) , just borrow, by allowing more crap to build up in neurons for a future crash cleaning. ... It would take some miracle, non addiction, sleep intensifier drug that made sleep lymphatic removal happen at a faster rate, to reduce sleep. ....Ah, education, so much better than any other approach. Probably, all Stimulants are vicious cycle, that brutally ages your DNA. I know plenty of people who abuse coffee to cocaine levels (police, judges, law makers). US army concluded 9 cups of coffee was same as lower dose of cocaine. Any drug, self educate. Otc or prescription. I have seen doctors mess as many people up with scripts, as the illegal drugs. Addiction is nothing to invite, court, or cohort. Steer clear, if possible of even the presence, treat addiction as a demon to be avoided in all forms. Think this is silly, and your life will suffer. Coffee gets many people fired annually, by accidental crashes and sleep interference.
The illegality of some drugs, implies consumers are stupid. Do not prove them right.
Anyway, I am against anything that promotes monopolistic practice, even if the health of the man on the street is sacrificed. Then, entire predation industries arise to eat off the flesh of the uneducated. Education should work, laws are meant to create monopolies. At least, it appears that way, if you look at every law passed.
Today anyone can read most any obfuscated medical paper, with no medical training, by simply long clicking the hard words. Not possible before the WWW.
