If you haven't already, look at investing in a Spot ( or Bubbler App for android, or the Apple equivalent) and setting up a Spotwalla account. Then put up the link here (and on Facebook) so we can keep an eye on your progress for safety.
The added bonus is (I think) you can submit spotwalla data as evidence with your trip.
Carry plenty of water and hydrolytes and alternate between one and the other.
