I think everyone is different. In the first week i had nothing but gurgles and movement in my abdomen area. BUt from day 14 to day 21 I was totally wiped out. It was one of the worst weeks. No energy, incessant headache, etc, it was just really horrible. But it lifted. If I recall correctly Humaworm said its different for everyone depending on the parasites involved, the state of the persons general health, and the degree of infestation.
I think mine was delayed because it was toxins from dead stuff flooding the body.; I was quite infested.
If you got your die off early, maybe it will be over early, too.
