I am just on the end of day 2 but I had flu-symptoms last night too. I felt horrible, nauseous, hot then cold, headache, exhausted, etc. I know that I was detoxing. I drank the laxative tea and went to bed. This morning I woke up feeling great. I think that period of detox sx lasts longer for different people. I was relatively healthy before starting so maybe it happened sooner and shorter for me.
I am hoping those symptoms don't come back once they are gone!
