I tried the ornithine again last night and as soon as I used it I had a bowel discomfort. Have horrible gas today but no stomach ache. Not sure what all this means. Maybe I have a build up of toxins or maybe I don't need as much of it. I'm taking 4 of them because she says to if you have sleep problems. I was sleeping very well when I first did the parasite cleanse but I'm back to being up most of the night. As far as I can tell it does nothing for my sleeping ability. Thanks for the response.
