Start taking niacinamide (B-3), non-flushing form only today. 500mg 2-3x per day, with food. Spread it out throughout the day. Plus Liquid IV (non-sugar version) for hydration and ensuring actual absorption of all your supplements. Water it down greatly (60-80oz water) and drink it throughout the day. You should feel a difference in a week. I prefer Liquid IV for electrolytes because it also has potassium, other B vitamins and sodium. This will ensure you have what you need for basic metabolic function/processing.

You must eat a low histamine diet and anti-inflammatory. NO SUGAR. I cut out dairy, sugar and gluten just to be sure. (On a temporary basis).

And stop exercising and over-exerting in ANY way. Don't try to run errands, clean your house, walk your dog etc. unless you absolutely have to (ie - go to work). Any gains you make are depleted with over-exertion.

I'm writing up my full protocol, which includes full supplements, amino acids and nervous system care, and will have it online shortly. Wishing you, and everyone here!, all the very best!
