You could always do like I do: not be a woman. No fibromyalgia for me at all. My mother and sister keep ignoring that advice.

But on a more serious note, that really has to suck. Autoimmune diseases are much more likely to affect women and are more likely to be ignored. There was a cool Radiolab episode on them. A hypothesis is that women have an overall more sensitive immune system because their immune system is suppressed during pregnancy so having a more sensitive one means you are less likely to get sick during pregnancy. Use of hormones like estriol seem to be helpful. But if you suffer from fibromyalgia, you probably know a good amount/all of that info and more.
