I don't know. I am in the process of shopping for a new doc, and that's something I want to talk to him/her about when I find him/her!
I read about it with the whole CFS/Fibro thing... and it's very interesting. I don't even want to bother taking this to my current Doc. He's on my last nerve.
I'll let you know what I find out, though, Kree! I'm so sick of all this CFS crap it's unreal, but as I read more I find that more things going on with me can be attributed to it... It's actually fascinating, if a pain in the tushie.
