Only thing I find is that I sleep in for the first few days. Not a bad thing since its holiday time!

I've not been ill yet while visiting the Philippines. I do make sure I drink bottled water only, but otherwise I eat food cooked in normal water, eat out etc with no problems. I try to avoid ice in drinks but not all the time (for example a soft drink with ice from Jolibee). I don't eat weird stuff though :-) I get one or two bites usually, nothing major. Of course it might just be the places I'm going that means I'm bitten less. Oh, and I love the heat, just don't overdo it when it is humid.
