Erika, amazingly I had pretty much the same symptoms when taking Amantadine. But by the time I took it, I had reacted to lots of drugs. And so was not surprised, and quit after a few days. Later, I thought that my reaction was because I have Porphyria (after I found out what Porph was and was ultimately diagnosed with it). I was very spastic, shaky, had eye trouble.
I also reacted severely to one Lyrica pill, given when recovering from Shingles, which are indeed as painful as childbirth--amazing! I was still on a walker, as my Shingles had been from hip to toe on the left. I felt I could not breathe well on Shingles; it felt like the partial bulbar paralysis I'd had many years before, when I was not dx'd with anything. It did stop the pain dead in its tracks but was threatening to stop ME.

Right now I'm depressed about my sensitivities because I even more alone, as I can't go to church (where most social life is) due to the toxins added to the office and the carpet.
They could have used steam clean on the carpet but wouldn't waste the pennies extra, so I can say they wouldn't waste even pennies on me, and I will not go back, as this has happened 3 times in the years I've been going there. Sensitivities are life changing.
