April, you are fine. Your body is still doing what it needs to do. I too, am like you. I haven't had any negative symptoms on my cleanse and I'm at the end of day 7. All my life I have been a very healthy person and come from long living relatives. I don't have any health issues and I rarely get colds or the flu. I believe that this has a lot do with not having any symptoms. I didn't even have a headache, which I thought I would, since I was a coffee drinker before the cleanse.
This is only day 7 for me and I feel like I keep repeating the same thing everyday in my journal, which is "today I feel good". The things that are happening to me are all positive ones and who can complain about that. Good feelings is what we all want. So don't quit. I believe that doing the cleanse will also help to take care of any future illnesses that I want to prevent. Prevention is the key.
All the best to you on your cleanse, April.
