thanks WI ... it's always interesting to me how timely things end up being -- turns out that my best friend ... who they thought had MS and have been doing all of those tests for the last couple of months ... they've now determined that she has the Restless Leg Syndrom ... and some other degenerative nerve issues that are very slow in their "progression" the combination has had some really scary effects in her life ... so it's always good to get a bit of information that can help educate. Thanks again!
