The
vision disturbances....how could I have left
that one off?

Blurry sometimes.....is it allergies or MS?
Heat intolerance. Well, now I actually have a good excuse for wanting to be inside in the A/C away from the heat, humidity and insects! Living in GA that is almost 9 months out of the year.
Potty issues 
. Not really a huge issue for me....as long as I am near the facilities. Since I can't walk fast....or run....I have to give myself plenty of time to get there. So there is alot of anticipation going on. Which is mentally tiring in and of itself. Especially if I happen to be somewhere other than home.
Cognitive. I'm so much better in the morning. By late afternoon/evening I'm tired and mentally spent.
All invisible symptoms to everyone but me. No wonder MS is so misunderstood.
