I found this Wikipedia article on botox.
http://en.wikipedia.org/wiki/Botulinum_toxin
I've heard of it being used for various medical issues.....not just cosmetic.....but I'm still wary of it. I mean, it's a neurotoxin! I have enough problems with MS. If botox doesn't work well or, heaven forbid, I have a reaction to it, that's just one more thing to deal with.
