Many many thanks for your advice.all of which I promise to SERIOUSLY take on board.Rosebud,what a relief to know that I have some way to go yet.I hope I didn`t come across as feeling sorry for myself.On the contrary....its just that these recent changes are so very noticeable therefore it was just a
hunch that had me wondering.
Interesting about the sleep and requip. I will request an alternative when I next speak to my neurologist.

Bless you
