Years ago when I was breastfeeding my last baby I was suffering with lots of headaches when I happened to read a small article in the newspaper stating that a new study had shown that one of the major causes of headaches was dehydration. I immediately began drinking lots more water and my headaches ceased. Unfortunately I did not keep the article and have not tried to locate the information since then but it did make sense to me and I have shared my experience with many of my clients with a fair amount of success. Has anyone else ever heard of this or know of any research in this area ? Ruth Bacon IBCLC Thornhill Ontario
