Thanks for this Annie,

Iam definatley not dehydrated, always drinks lots of water, as I've ended up in hospital a few times when I've been sick and badly dehydrated.

I will mention my high heart rate to my gp, as he is more receptive to these things, and my neuro nurse, she is GREAT, she just sits and talks to me and then says " your breathings a bit bad, or, your eyes arn't too good today", she is a very special lady!
thanks again
Kate
