What? You never heard of Ritalin? Actually, you’ve just heard of Adderall, which is also used to treat ADD. And both are being illegal used by college students for concentration, altertness, and stay-awakeness.
Both drugs are in the amphetamine family. So, bah humbug to these whippersnappers, my generation was using speed back in my college days long before these Gen Y copycats.
Like amphetamines, it is illegal to take without a prescription, and they have side effects, and they’re addicting.
Stick to clean, moral, and legal living. Get plenty of rest, exercise, and good nutrition.
Stick to caffiene as a legal alertness aid, if you must. Or, get a legal prescription from your doctor for modafinil (go ahead, Google) for what appears to be (so far) a non-addictive, safer alertness med to replace caffeine.
Peace.
