I'm guessing it was because you were de-hydrated. Everyone stresses the importance of hydrating your body before doing these flushes. Shellycat could probably give you a more detailed clinical answer. I'm sorry you had such a bad experience. But whatever you do, DON'T have anything surgically removed. I had my gallbladder taken out thinking it would solve all my problems and I'm still have the same problems only worse. Research liverdoc.com and sensiblehealth.com. They will explain how the liver works. You'll probably need to give us some more info about your body. Hypoglycemic? Candida? Age? Weight? Thyroid? Symptoms of present illness. Why were you flushing? (Maybe you've already posted that here someplace.) And listen to some of the experts on this forum. They are very good and knowledgeable. If Shellycat doesn't respond soon then send her a personal email. She will answer but there are others who have lots of experience with these flushes. Hope this helps and that your lip doesn't hurt too bad!
PS. About a month ago I just wanted to die cause I was so sick. Now I'm gettting better each time I flush.
