When I’m thinking through a hard problem something I’ve learned to feel/notice is an oncoming massive migraine unless I supplement some magnesium, multivitamin, nootropics or easy to digest amino acids to give my brain the essential elements it needs to perform. I recall our bodies do not produce magnesium. This advice is on top of being properly hydrated, otherwise I will have impaired cognition and brain fog until proper hydration + supplementation is achieved. Can anyone relate?
