You may be getting the effects of "die off". I think you need to drink lots of water. Maybe buy a zapper. I read somewhere in her book that parasites attach their mouths to the walls of your stomach. They get the best nutrition, and you get whats left. You are stirring them up and killing some of them.
Keep going and don't stop. These cleanses take months or years. You learn more as you go.
Some one here said that orthanine stops the bad effects of ammonia caused by dying parasites.
What better study is there, than your own health, getting results as you go.
