Hi Betagirl, nice to see you here again...
well, for us, anyway ! I'm sure you know what I mean...
I would be aiming for all sorts of pretty pictures - glorious reds and scarlets, no milky white at all...and no browned-off doctors because the moviprep didn't work !
And as you run to the loo for the 25th time, remember the old Garfield cartoon saying, "No guts, no glory..."
(Sorry Randy, you are of course the exception.
)
