thanks for the response. I actually have read many of the NPN and detox posts and they had me worried, but then I realized I was getting steadily better until bam I just crashed. Which was the same thing that happened to me when I did the liver flush. I didn't change any of my food sources so while i had been concerned about their brix content, I also realized that I had been steadily getting better and more alkaline on them so it seemed unlikely they could be the reason.
But I did come here for help and you've given me something to think about. Recently I've begun getting all my vegetables from a biodynamic farm. Soon as my budget allows I will get a brix refractometer and look further into this. I'm also going to post and ask on sicknesshope. Thanks though, I know how rough it is responding to people when they think they know the answer to their own question.
