I also experience the migraines and have noticed the correlation between them and the severe constipation. I talked to my neurologist about it and he said the constipation is a trigger for my migraines...like chocolate or caffeine is for some. I don't know if I completely buy that because I think it is just a mess of toxins overloading my brain. I get about 3 or more a month right now and they usually knock me out for a day or two...this includes being in bed with the pillow over my head! I will let you know after my surgery if they subside, okay?
