Well, it was over in about 15 minutes! Easiest diagnostic tool/procedure ever. They said the results would be ready in two days, but I won't get them for another two weeks, when I meet again with the neurologist. Again, thanks to everyone who gave me ideas on what to wear, what to expect, and how long it might take. You guys are the best and I'm glad to know that I can always come here and get some good advice.
