Snoopy, thank goodness you're feeling better, and you're a smart woman to do the research. Thank you for the links.

Funny I see Carbamazepine on the list. I had such a crazy reaction to that stuff day 2 of taking it... it changed my pitch perception of music. I was bawling my eyes out while my ex bf listened to the same songs as I had on the same computer and said, "They sound fine to me". I was scared I had permanently damaged my brain or something. Thank goodness it resolved in 24-48 hours.

It's not listed in the warnings, yet I truly did experience it. I only made the connection when I sat at my pc frantically searching "Music change" "Pitch change" with Carbamazepine. Then I found cases like mine.

And this link "There are also reports of an auditory side effect, whereby patients perceive musical notes about a semitone lower than their actual pitch (so middle C would be heard as the note B3 just below it, etc)."

(not the best resources surely, but I'm not a medical Internet savy person, so if you find any reliable resources, please post them up, because I'm still curious about this side effect!).

The drug was originally prescribed to me when Trigeminal Neuralgia was suspected prior to MS being in the picture.

Oh yeah, I should have added. I told my neurologist (current) about this side effect that I had, and that I would never take the drug again. He looked at me with a smile and said, "That means you are musically trained to perceive that. You should start playing an instrument!". LOL. I love my neuro.
