Unfortunately we get winded by the simplest tasks. I have to rest inbetween the simplest chores. As soon as you complete one task or whenever the sx kick in just sit on the couch to rest. I find too much activity does make feel worse. PT and Neuro both say "Conserve Energy" You will be able to find your own comfort zone.
Rest/Naps really do work for me. Good Luck! my friend :>)

I know what your talking about I feel it as I write, I feel it so much inside it makes me sick to my stomach. Do you also feel sick to your stomach when this is happening to you?
Feels like nerves are jumping all over?
I have been feeling this for days and not do anything and feel it. It will drive ya bonkers.
I think it is demilen of the nerves and firing gets interrupted, I get the shakes sometime like a volcanic eruption is about to accrue.

I can relate to that too and its tough finding your limit. And I think that you should be careful with the energy, vacuuming and such things are exercise and do burn calories too. Check on About.com how much!
