Thank you for sharing your experience. Sorry to read about your situation. I also tried vegan in my younger years which gave me nightmares as it was not compatible with my genetic makeup. However, plant based diet work for some people if they formulate their diet well. Finding some essential nutrients (eg vitamin B12/D) and especially bioavailable proteins is a challenge. To extend the meaning of your great story, I share my documented experience https://medium.com/sensible-biohacking-transhumanism/low-fat-diets-gave-me-unbearable-nightmares-b98a9df8aa3
