I shall be logging off the list after checking my mail on Monday morning. This is because I am having a DBS on Tuesday 12th. I anticipate being back on board somewhere around the 21st. Because of this, the extremly short 'on' times I am experiencing (resulting in any lengthy correspondence taking me several hours), and my desire to spend some with my family prior to surgery I regret that I cannot give the discussion I recently initiated the attention it deserves. I should have thought of this before I started. Please accept my apologies for my poor timing. That said I hope that others will pick up on some of the interesting points already raised and that anyone so doing will be kind enough to cc me a copy at my private email address (see below) Cya, Dennis. +++++++++++++++++++++++++++ Dennis Greene 49/dx 37/ onset 32 There's nothing wrong with me that a cure for PD won't fix! email - [log in to unmask] Website - http://members.networx.net.au/~dennisg/ +++++++++++++++++++++++++++
