Last year, I spent 6 months travelling around Asia, I made the decision to not take the Malaria pills. My reasons for doing this, was the amount of time, I would be on such a strong drug, which causes a whole lot of other problems. I was personally comfortable with my decision and made sure I was really careful when I was in the Malaria areas, for example covering up at dusk and dawn and sleeping under a net etc.
Only you can make the decision. The best advice I can give you which will save you a lot of money, is waiting to you are there to buy your Malaria pills. They are generally up to date, the the country Malaria strand and a lot cheaper!
The very first time I went to Laos, my doctor here in Brisbane, AUS gave me a pill that didn't even work in Laos! Check out the medical web sites and have the name of the pills written down somewhere for when you arrive.
