I know nothing about fibromyalgia but a bit about headaches--the 3 day migraines, the kind that when your husband walks across the carpet, the noise & vibration are excruciating. Thank the good Lord, I outgrew them. I know now after reading the book titled something like "Your body's many cries for water", that I could have helped myself part of the time. I'd advise anyone with any illness to drink at least the recommended 8 glasses of water a day (Coffee etal doesn't count as it makes you lose more water than you took in).
