Breezy,
Like Kim mentioned, there are some drug combinations that just don't work well. It isn't always a matter of bad interactions, where the combination will cause problems. That's the type of thing the pharmacists check when filling a script. But knowing when a combination will reduce effectiveness is much more complex. That's one of the reasons I see a pain management clinic. I could easily get my GP to write me a script for a pain killer, but the Pain Management people have more experience with all of the different cocktails.
It's frustrating to have to wait to see a specialist, I know. Hang in there, though.
Kim was suggesting some simple meditation. That can really help in getting past some of the hard times.
I hope you get some relief soon.
Mike
