I've had bouts where I feel revved up and want to run off screaming into the woods. Usually after starting or increasing herbs. My herxes seem to often be delayed, around the 3 week mark. Herxes can kind of snowball for me. They come on slowly and I barely notice. By the time I realize it's a herx, I'm ready to run off screaming.
Anyway, both the herbs AND the minerals and vitamins can cause herxing. Zinc, selenium, B vitamins are all in Klinghardt's KPU protocol. If you were initially deficient, supplementing those can cause the body to release heavy metals, which can cause some of the symptoms you described.
Instead of supplementing daily, start with 2-3 x week and go from there. If needed, you can reduce the dose on the herbs until you feel better. Then increase one at a time, slowly.
