This post is for anyone suffering from head pain. I have had headaches for as long as I can remember. It was difficult to tell if they were sinus, migraine or allergies. One side of my face would typically be very painful with the nostril closed up. Supplements and allergy medicines worked temporarily. Removing eggs and dairy products worked as well, but the headaches would always return. After reading EC over several days, I came across a post on 5htp and learned that SAM-e, 5htp and tryptophan may all support serotonin in the brain. Well, using kinesiology, I tested for tryptophan. My head was still hurting after mega doses of pharmaceuticals but I ran to the health food store to obtain tryptophan. This is day 3 and head pain is 90% gone. Actually, the pain went away after the first day. This is a miracle and I hope it lasts! I take 3 capsules (575 mcg) in the morning with food and follow up with one or two capsules in the afternoon. I never suspected low serotonin as a culprit for headaches because I'm always happy and upbeat and ready for a laugh. If apple cider vinegar, vitamins, magnesium, allergy meds, environmental toxic removal, mercury filling removal, net pots, and chiropractor adjustments don't work for you then it may be something else. Please try this remedy!!! I will repost updates in a few months to make sure the remedy is still working.
