Have you tried encapsulating the green flesh only acolon? Doing this I almost never experience much stomach irritation, and when I do, taking a puff or two of weed kills the nausea. Only when eating the flesh raw or making a tea I find there to be a great deal of stomach irritation.
“Surrender is inner acceptance of what is without any reservations. If you have lived long enough, you will know that things “go wrong” quite often. It is precisely at those times that surrender needs to be practiced if you want to eliminate pain and sorrow from your life.”
Eckhart Tolle
