I dealt with headaches but they weren't severe. I think the coconut oil can give you bigger headaches because it kills candida and can worsen die off symptoms. The ingredients in Humaworm already kill candida. I personally take organic extra virgin coconut oil, but I didn't take it while taking Humaworm. I would say try taking a good magnesium supplement like chelated magnesium or magnesium citrate (not magnesium oxide or magnesium aspartate though because the first one is a laxative and the second one has aspartic acid which can be neurotoxic), and definitely try to exercise and sweat to lessen die off symptoms. I personally don't like to take Tylenol for headaches. I think the magnesium should help a lot for them. As for being very hungry, maybe the parasites can tell they're being attacked and are trying to get every last bit of food before they die. Who knows, but wait it out and see how long this lasts. I don't think it will last that long.
