After giving up psychoactive substances for a long while, I hoped I might find my definitive baseline but all I can conclude is a lack of one. Only in contrast to an altered state of mind can we really judge one to be at baseline. I tried, I really did, sober for months at a time. I would not eat properly when I was studying and it would be most unpleasant, Restless and irritable, I'd say I was 'hangry'. This hammered home one thing, one thing alone: as food metabolizes certain nutrients are absorbed into the bloodstream, some of which may permeate the blood-brain barrier. Deficiency or excess of common compounds contained in food can affect our consciousness, For example, postprandial somnolence. Lack of nutrition causes contrasting effects and an aggravated excitation manifests in a hungry human just as sleepy sedation occurs in the sated **** sapien. I do wonder what effects diet has on neuroplasticity. Vitamins and rich-foodstuffs must have some effects on cognition. It should hence be essential in building a nootropic stack that one keeps track of their diet so that every calorie can be calculated and tallied. Thereby we might more efficiently measure our natural baseline and hence perfect a method of stacking.
Keeping in mind what consumables (foodstuffs, vitamins and psychoactives, etc.) have synergy will allow identification and perfection of a stack as well assessing stack-to-task suitability.
