Ask HN: Specific Smart Drugs and Nootropics that you recommend?

In an age where LSD and meditation have been shown to increase brain connectivity and cerebral density (respectively), I look now to use the next ~two decades of my life for very demanding projects. So some questions, and some insights. Firstly, my discoveries: Your neurochemistry is of paramount importance (second only to your attitude, unless your body/brain is totally depleted and then it's primary). Neurochems that your body releases during cascade interference (with things such as MDMA and LSD) are not ingested directly to the body, no, neurochems actually come to your brain through digestion of what you've eaten, making your diet paramount. Your diet and a healthy gut biome ("party in your belly" as I like to call it) depend on probiotics and yogurt to keep your intestinal bacteria awesome. Subsequently, what you eat will become excellent amino acids, and those can subsequently become the perfect neurochems for your brain, thinking, loving, feeling, seeing, etc. Questions: Favorite natural supplements? Favorite prescription alertness enhancers? Can I eat Modafinil every day for the next 20 years and have no huge detriment to my body? Can I somehow monitor the status of my body and organs without going to a doctor, to see if there's any unusually excessive or speedy wear and tear? Thanks a lot everyone. Looking forward to moving society closer to paradise with you all.
