I think it is ornithine. You could also try a coffee enema, which I am doing. It is so expensive ordering everything, but, then again, I use organic coffeee, so that is a little expensive there. I had a horrible headache Monday nite, and terrific intestinal spasms. Total insomnia on Tuesday nite, and wasn't sleepy at all yesterday. I hope these side effects go away soon!! I did sleep last nite but had to wear a back brace to hold my insides because they were shaking so much. I have intestinal problems, and that is why I started zapping. I only began zapping on Jan. 20th. I tried the coffee enema, and that does help.
