Well, I feel that my going on about your W and the possibilites has added to your stress level and for that I am sorry b/c I know you have enough to worry about.

I would like to suggest that you speak to her about getting a complete battery of blood tests before you mention anything about seeing a IC. She will probably protest, but you can express your concern for her radical mood swings. You might even find better words to use rather than mood swing. That usually implies "hormones" and some women just resist the idea. But if you put the words IC and doctor in the same sentence, I think she will acuse you of trying to "fix" her. Know what I mean? There are many women who feel that way when their H's suggest that to them. Somebody who is better at wording things might be more help than I am.

I suppose she knows your friend is aware of the EA and can observe her?

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
