well it might have been your intestines - I'm not sure but I think if they're not clean, the mixture is likely to pass through very quickly - can anyone verify that? It's just a thought. I remember similar symptoms once I started with my LF. Next to it - my head would get a bit extra oily! Once I took care of my bowels it disappeared. The only thing that bothers me is WHY it got improved, I'm just guessing it was intestines.
