My daughter and I took Lariam for our last visit to Indonesia and noticed extreme fatigue as a side-effect. You might want to research a new anti-malarial "Malarone" which is expensive but supposed to have few adverse effects.

The bugs are HUGE in the Okavango, I remember when we flew out of Xaxaba airstrip the tsetse flies smashed against the aircraft windscreen and there was blood everywhere---yech. But we looked out the side windows and saw herds of giraffe running right below us.

This was years ago, we camped using local guides who poled us around the Delta in their mokoros (hollowed out log canoes). At the end of each day out guides would select an island and scout it out before telling us where to spend the night. Six of us set up camp each night around a large campfire and slept feet-outward in a star arrangement---so if a lion came into camp we could all awaken and yell to frighten the lion. I thought this was a big joke, but when we got back to Jo-burg we read about another camping party a few miles from us who were attacked by a lion, they scared the lion away just as we had been told. Whew...

You are wise to take your teen to Botswana now, I think all the wild game will be gone in not too many more years.

Have a wonderful trip.
