Thanks a million everyone.
Mathfox - will go to bed on arrival and set alarm for 5am. Suits me to be on the road ASAP to drive 130km.
DavidReidUK - I am worried about that connection. Its the one American came up with so I booked it. It would be hell to be on the bus.
Exxb - will set my watch, try to sleep and adjust meal times to -8 hours as soon as I board.
Farci - An odd time ;-) Googled the water suggestion and came up with 1 litre every 5 hours.
Thanks once again, you've all been a great help.
