I am unsure whether the coconut would be a major detriment or not to the cleanse, but I imagine it is still an improvement over what you ate pre-cleanse. I wouldn’t worry too much about it and learn from your experience and move on.
We have a strict forum food list if you are interested; me and able feel that you’ll progress a bit faster with this food list when compared to the websites or other websites food lists. Email able900 if you are interested in a link to the list.
I think you made a good decision to not continue with the coconut and you’ll probably feel better without it.
Later in the diet most foods will barely be a problem if not eaten too much. As time progresses you’ll be able to handle more and more good tasting stuff.
