My suggestion (if you want medical advice go to a doctor), based on experience in Africa..
Don't take anything; where long clothes from dusk to dawn (long trousers, long sleeve shirts), sleep under a net, and use an anti-mosquito cream, like tabbard (better than the sprays and you can get more even coverage).
Keep plenty Artemisinin handy - make sure you get it from a reliable source e.g. before you go in country (there is a lot of fake on the market in Africa - even from the ER in hospitals who were duped!).
The moment you feel poorly take the Artemisinin. (headaches, fly like symptoms, tiredness)
If you use it as a prophylactic it will make you used to it and reduce or remove its effectiveness.
