Johnz, Just so you know, you can only take most malaria medicine for around 3 months before it starts to damage your kidneys (or is it liver?).
The best protection is mosquito repellant and long loose clothing, and the mosquito nets for the bedroom.
Pills like Doxicycline is great to have around as they are the treatment as well as the prevention medication. Soooo instead of using them as a preventative, take them when you suspect you have malaria and then get out of the country to the nearest 1st world hospital you can find.
For the guys that are thinking about hitting the congo... there are far more and safer countries around africa to try first before heading there.
Specially when you dont have much experience and looking for your first job.
