I'm Sooooooo sorry you're in the midst of so much pain... My most recent PEA info I posted over at Sandi's, but I'll try to find more about what I've read and post here for you. The effects of PEA wear off in about 18 months and switch to endorphins.
Unfortunately, unless your wife doesn't want to learn and go through withdrawal, then you can't control that. Ironically, the best thing for her...and you, is to exercise, and focus on making your life the best it can be.
I'm not sure if she has committed to working on the M with you?
I see my IC today... And even though he's an hour away, so worth it!
Today is good... The Omega's and walking really helping.
