>>12551628I take NAC and 3-5 grams vitamin C in the morning. I generally try to eat fats instead of starches or protein, though it varies and I haven't really optimized that. I don't drink caffeine unless there is an actual reason. Confounders for my testimony are that when I've needed to do a lot and sustain it I've tended to get high af on cacao which achieves exactly what you seem to be after in the short term (especially when fasting), but in the long term net burns you out and really modifies how your mind works (the mode and direction of the claritym divergent and lateral thought is emphasized, convergent thought is reduced) and how energy is allocated throughout the day. The stories from central and South America are true, "a man who has eaten cacao can easily march all day and all night with no food", however do not let it deceive you, there is a cost and you can't draw on that indefinitely. Cacao is a drug and should not be abused. Otherwise I would make sure my vitamin D was adequate, and would eat brazil nuts for selenium. There are a ton of herbs that can facilitate mental clarity but I don't really feel like listing them because let's be real, no one is into that shit. However in short:
-Polygonum multiflorum
-Gotu kola (centella asiatica)
-Ashwagandha (withania somnifera)
-Ginkgo leaf (ginkgo biloba)
-Rhodiola rosea
-Ginseng (very estrogenic, not a male herb long term)
-Schisandra berry
-Shatavari (asparagus racemosus, very estrogenic)
-Bacopa monierri
Caffeinated:
-Guarana seed
-Yerba mate
-Guayusa
Exercise, intermittent fasting, cutting added sugar out of the general diet, and so on also help a lot.
