Barb, so sorry to hear that. I know i've said this a few times before, but I don't know how you cope with not being able to sleep. My Oz experience (several weeks ago now) still has me shuddering at the thought and that was only a couple of days !
I guess the best thing is just to take it easy and rest even though you are not sleeping. I know there is no substitute for sleep, but at least if you are not physically doing too much, you might feel a little better.
You could always try my "Oz Remedy" tonight.....several glasses of chardonnay.
(although I did pay for it the next day, lol)
