Tired. .I spent over two years in PNG and was fortunate not to have contracted any form of Malaria during that time..I did not use any form of anti malarial drug BUT I did take two GARLIC tablets daily. I was told that garlic acts as a natural repellent through the pores of the skin and it certainly worked for me. People may laugh at the suggestion but they laughed at the Wright brothers as well...
Good luck
