Modafinil comes with a litany of side effects, and is not for everyone (<a href="http:&#x2F;&#x2F;www.drugs.com&#x2F;sfx&#x2F;modafinil-side-effects.html" rel="nofollow">http:&#x2F;&#x2F;www.drugs.com&#x2F;sfx&#x2F;modafinil-side-effects.html</a>). It also has &#x27;minor&#x27; interactions with amphetamines like Adderal (<a href="http:&#x2F;&#x2F;www.drugs.com&#x2F;drug-interactions&#x2F;modafinil.html" rel="nofollow">http:&#x2F;&#x2F;www.drugs.com&#x2F;drug-interactions&#x2F;modafinil.html</a>), a common &#x27;card&#x27; in the &#x27;stack&#x27; that many nootropics proponents use. Doctors come with years of training and pay a lot of money for it. Before going on possibly psychotropic drugs, talk to them, not some random dude online.<p>That it &#x27;enhances&#x27; your brain is an incredibly complex statement too. Define enhance, define brain, define your brain. Is your enteric nervous system part of your brain? Will these drugs effect it too and enhance it? How do these drug&#x27;s enhancements effect the nerves that control digestion, circadian rhythm (modafinil &#x27;promotes wakefulness&#x27;), or the functions of reflexes or other autonomic processes like valve and sphincter control?<p>&quot;It&#x27;s good for graduate students to understand complicated math or engineering concept.&quot; Read that again. I don&#x27;t know what crazy place you are in, but if you thing that taking small doses of very powerful hallucinogens is a good way to get work done, you need to find another job very quickly. Yes, it may unlock  more &#x27;science&#x27; or breakthroughs, but in doing so you put your body and more importantly you mind and sanity on the line (<a href="http:&#x2F;&#x2F;www.popsci.com&#x2F;science&#x2F;article&#x2F;2013-08&#x2F;fyi-can-acid-trip-really-give-you-flashbacks" rel="nofollow">http:&#x2F;&#x2F;www.popsci.com&#x2F;science&#x2F;article&#x2F;2013-08&#x2F;fyi-can-acid-t...</a>). Yes, it is a small risk, but one you don&#x27;t have to take.<p>Yes, Steve did talk about lsd and it being  powerful experience for him (<a href="https:&#x2F;&#x2F;www.goodreads.com&#x2F;quotes&#x2F;542554-taking-lsd-was-a-profound-experience-one-of-the-most" rel="nofollow">https:&#x2F;&#x2F;www.goodreads.com&#x2F;quotes&#x2F;542554-taking-lsd-was-a-pro...</a>). But from the quote, it seemed to be more of a 1 time experience, not a habitual thing of micro doses. Steve was going to be Steve with or without lsd, I think, though he seemed to think it helped motivate him.<p>All in all, eating right, sleeping well, and getting exercise are the best bang for your buck. As it has always been.
