i did a couple master cleanses (bowel cleanse)
a parasite cleanse
this cleared me of all my chronic headaches. i think that there was toxic crap setting in my bowels that was causing my headaches.
also Sugar and artificial sweeteners can make you feel like this.
if nothing else try the Bowel Cleanse thing. i am so glad that i hardly ever get any headaches anymore. before i was getting a couple every week. cripping i am going to puke this hurts so bad and advil barely works ones.
