Sorry, I couldn't remember and was too lazy to look it up. My wife may let an uber bitch in her Audi, though, if you ask nice.

I am totally convinced the trials and errors of uncharted territories just piles on additional side effects that are often worse than what you are being treated for and are a total crapshoot as far as how long they last. I had something that was working for years fine (thank you Gary for the suggestion years ago) and my oncologist moved away. Now they want to use Botox with some issues of it's own or start burning nerves. We tried some lidocaine in the neck to "simulate" expectiations of botox and I could barely move my arm, my ear was numb and my hearing on that side sounded like a blown speaker for 4 days. The weather was changing so I did not notice if it contributed to the changes in swallowing. I was assured if I could not swallow, it would resolve itself in 90 days or so. I am a bit claustrophobic and I suddenly felt like someone was holding my head under water just to hear it!

Anyway, something takes the edges off while I embark on a jurney to seek more knowledge.
To paraphrase, this too shall pass, but I will add only if you put forth the effort to seek solutions.
