Well, of course I am only on Day 11, but I have not found any problem so far with detox or discomfort, certainly not feeling "ill" and only weak in a positive way, assuming my body is redirecting energies. This does not answer either my question or the question above mine I was responding to, and I think is overly dire and pessimstic. Vegans are not _that_ toxic, by the way, unless they eat a lot of Sugar and soda.
I am certainly not "failing" at my own fast for health,etc. (other reasons than weight loss), the sense of being physically stressed or overwhelmed, and neither is mbryan.
