I have a fairly new client that has suffered from terrible migraines...often two a week that last three days each accompanied by lots of medication. Last week she had her third colonic and reported that she had not had a migraine all week. Yesterday she came for her fourth colonic and was in the early stages of a migraine...first in two weeks, but refrained from taking any meds before her session...by the end of her colonic her migraine was already going away! She also attempted the Ultimate Fast a few weeks back, but caffeine withdrawal brought on a bad migraine that required medication and left her quite constipated...so she stopped the cleanse until the colonics get her going regularly again. A good Colon Cleanse can most definitely benefit those suffering from headaches and migraines... and a whole lot more!
