<p>Easiest option:</p>
<p>Drink yerba mate. It is a tea from Argentina and it is delicious enough that I drink it in spite of it containing caffeine. It has about as much caffeine as black tea or half a cup of coffee, but it also contains theobromine(caffeine-like substance found in cacao), and theophylline. It is the only drink to contain caffeine, theobromine, and theophylline all together. This cocktail of xanthines will keep you alert by stimulating your heart and acting as a vasodilator, while allowing your smooth muscle tissue to stay relaxed. It affect the nervous system less than caffeine by itself.</p>
<p>Harder (but possibly better for you) option:</p>
<p>Listen to binaural beats with theta waves sometime in the middle of each day for about half an hour, which acts kind of like a power nap and reduces your sleep needs, and will help you internalize what you learn more effectively.</p>
<p>Hardest (but most reliable) option:</p>
<p>Learn to meditate well, which also produces theta waves, but perhaps more reliably than binaural beats. </p>
<p>Also here are some other random things you could throw into the mix:</p>
<p>Stay hydrated: Most people are at least a little dehydrated, and there are many similarities between symptoms of dehydration and sleep deprivation. This is a sustainable method.</p>
<p>Cold showers: Makes you more alert and makes you feel better and consequently it would be easier to look awake. The feeling better has to do with norepinephrine and beta-endorphin, which are mostly regulated from the blue spot (locus ceruleus). Another effect is that your skin will look better and healthier, which people will associate with looking well-rested. This is because hot water dries the skin more than cold water, and I think it might also have something to do with circulation. Start with a cool shower and then gradually go colder day to day. Your body will get accustomed to it.</p>
<p>Multivitamins and Omega-3 fish oil</p>
<p>Exercise regularly</p>
<p>I can’t think of anything else right now (I have a cold), but let me know what you think of what I’ve suggested so far. :)</p>
<p>On a side note, anyone else notice how limited the dictionary on the CC spell checker is; every time I start using big words, I start seeing red lines everywhere just like in Google Docs.</p>
