I'd look into your diet.
Calcium is a massive stimulant when it combines with the catecholamines.
Omega 3's lower osteoclasts which release calcium from the bones unfortunately the western diet is high in omega 6's which will kill you slowly and contribute to poor health outcomes over a few decades. If you increase your omega-3's, your neutrophils will increase in size and B12 helps prevent neutrophils from hyper segmenting, which means a better quality of neutrophils. As vitamin C is stored in neutrophils, making it a highly toxic environment for pathgoens, your vitamin C levels will also increase. High vitamin C helps increase the iron content in the body, and Iron based Reactive Oxygen Species (FeROS) generate the most amount of heat in the body, which is why we feel warmer as kids compared to elderly people.
Vit K2-MK4 can also help reduce calcium from the bloodstream, I take 5mg of this before bed and sleep very well, better than benzodiazepines, anti-histamines targeting the receptors in the brain which block the feedback look that affects sleep, and other herbal sleep remedies.
If you are aware of the concept of having a glass milk and biscuit before bed, this is because casomorphine in casein in cows milk constitutes about 80%-90% of the protein in cows milk, and casomorphine is a biologically active opioid peptide very similar to morphine!
Tyrosine found in food, like cheese can act as a stimulate, especially if your copper intake is high, which could explain why the RDA for copper has recently been lowered even though copper is needed to make some interleukins which target a wide range of cancers! Tyrosine can make noradrenaline in the brain, a stimulant, which could explain the idea that eating cheese gives people nightmares. When Tyrosine is combined with Cysteine, it improves the mucous membranes so could help reduce your dry stinky mouth, the two make pheomelanin, which is better than just tyrosine on its own which makes eumelanin, although both an an antioxidant effect in the brain.
Thats just an outline of some of the things that can happen in your body when you eat, but some chemicals are better taken when you wake up (copper, tyrosine, cooked English breakfast), some are better taken when you want to go to sleep (carbs, tryptophan).
I mention carbs and tryptophan, because tryptophan is blocked or crowded out by about 5 or 6 other amino acids at the blood brain barrier which reduces the ability to get serotonin and melatonin precursors into the brain. The Kynurenic pathway which converts about 95% of tryptophan into about Also remember that RDA's should be viewed as the minimum recommended amount for a maintenance dose of you are considered healthy. GP's never ask about people's diets, because they prescribe licenced drugs, where any liability falls back on the drug company, and most people don't have the resource to fight big business as they generally have met the legal requirements laid out in law.
Not saying all drugs are bad, but I think we underestimate the importance of diet and how the food has changed over the last few decades to get us to eat more!
