Hi Hope,
I just was wondering if you have looked at some of this from the nutritional/vitamin point of view?

If you aren't eating well - as well as the extra pain and stress - they do deplete the body resources from a nutritional standpoint.

I used to know all of this stuff to recommend to you - but now I'd like to suggest you visit our Vitamin and Supplements forum and give it a try.
there are drug /interaction checker links in the useful sites too.
