Nicky, I don't think an antidepression would hurt. Mine did help me awhile back, and who knows, maybe I'd be a lot worse now without them? (right now, I'm too scared to stop them or change them to something else)
Last year, I do believe they helped w/ the constant muscle pain. And they do also help me sleep. The med I am taking is an old one (as I'm reminded here), but there are so many new ones now, maybe you'd have some good relief from one of them.
Maybe if you don't get more responses here, you could start a thread, asking about
anti-depressants. There are quite a few on this forum and it might help to get their input and see what they are taking.
Dowa, how do you get your transmitters checked? I have never heard of this.
