I've suffered from migraines for a good part of my life, mainly hormonally related. Some days all I could do was lay in bed and try not to move, with severe head and neck pain plus nausea. I tried chiropractic, dietary changes and standard medical approaches, but none worked very well. At best they treated the symptoms after the migraine appeared. Then I tried OHCO-Flow. What a difference! I have gone from knowing I was going to have 4-5 severe headaches a month to having 1 or 2 minor ones. I still maintain a good diet, but OHCO-Flow seems to have balanced my system. I have my life back -- no matter what time of the month it is! Thank you, OHCO. - Annette S in Aspen Park CO
