malaria prevention
"Be advised that any medication can have averse reactions on anybody. My experience with Malarone was when I traveled to Cambodia for 2 weekw. It took about a day before it started but Malarone completely incapacitated me with a constant level of nausea. I could not eat nor was it worth leaving the hotel because I was weakened by it. l, too, had to discontinue its use for the entire trip, completely soaked in deet instead. It would be advisable to try malaria medicine several days before you leave for a  trip to any questionable location. Ironically, in the middle of 105° F temperatures,in November, in full sleeves and pants, I never encountered a single mosquito."
