About a month ago, I switch to "Mostly Not Plants" and have seen many improvements (less fatigue, better sleep, more restful dreams, less anxiety).
I still do eat a small amount of berries and a few other plants here and there, but the vast majority of my food is now meat, eggs and dairy.
So much better and I have no temptation to go back to eating what I was before, which was very healthy compared to the Standard American Diet.
