A simple, straight answer to your supplementary question, Boboutofkenya: yes. We were issued with Malarone, and required to take it, and I never heard of any bad effects from anyone. However, I am aware that they can and do exist.
Whatever you decide to do, I would give you two pieces of advice: don't listen to any old wives, and there are many; and when you return to a part of the world where malaria is not prevalent, U.K. for instance, carry with you a letter explaining that you have visited a malaria-prevalent area, and include an emergency telephone number. So, if you suddenly keel over, the medics can do a quick diagnostic test, rather than thinking you might have flu/vertigo/be drunk etc.
