Well done. Malaria is a serious issue.
I used to spend considerable time in risky areas of India, even though I did have some
slight side effect I stuck to tablets.
Few times I needed to stay quite long periods so could not take them.
I tell you, I went to extraordinary lengths to protect myself.
Jamie, if you will be in high risk area and especially sleeping without A/C I would suggest investing in a good mossie net.
Oh, by the way, (slightly off topic) don't forget the handy pocket size packs of wet-wipes
