You all are so wonderful, and I truly enjoyed and appreciate your responses.
Chris-- I do understand what you mean about balance issues. Though so far I have a case of "MS Lite",shortly before my DX in '93 I was experiencing visual disturbances resulting in 'vertical diplopia' ; the kind of double vision where images were one atop the other unless I moved my chin up or down to line them up.(I was in a bowling league at the time.. and, seeing two set of pins, was the only one getting the occasional 20 pin strike!

Though it all went away within a week or two,that and a subsequent attack where I could not walk AT ALL for ten minutes left me with some residual balance issues that are still with me. Unlike perhaps the kind in Yoga where one is more or less stationary,mine are related to going downstairs fast or running fast on any surface.. Can't do it.. I feel unsure and unsteady. Weird.
Curious--Thanks for the tips. Yep-- I've always got my little water canteen handy.I'm not doing anything too radical , and the Y is familiar with MS and the trainers understand the issues at hand, so they do watch out for people like us. Even in January-- where everyone and their brother are in resolution mode,the place is not awfully crowded, so we are getting good individual attention.
I thought I'd be in a lot of pain today-- but only felt slightly achy, so when I went out for some errands I walked to and fro--got some fresh air and all's well.
And as for Chocolate-- YESSS--the darkest chocolate in small amounts.
I have it with my afternoon tea-- (Chris, I'm from a British family-- Dad born in Wales, Mum in India-- her Dad ran a tea plantation in Mysore)
All my life,TEA has been essential--morning, afternoon and sometimes at night--- dark and strong, with milk and a bit of sugar, please.

Cindy-- loved the treadmill clip..So far I've avoided that particular mishap.
Thanks all, and take care.
Cheers,
Bronwen
