After having the allergy clearing done for 12 of my food sensitivities, I have not experienced a headache that was common for me to have a few times every month. I can eat eggs, dairy, wheat without any symptoms. I can't tell you how excited I am to be rid of that headache that would really affect me for days at a time after eating something that my body was not processing well. I look forward to finishing my allergy clearing and being able to build my diet around nutrition rather than a list of things I can't eat. Thanks so much for introducing me to this technique.
