i'm diabetic myself so this is quite interesting. so this basically checks the level of acetone in your breath and gauges your blood sugar levels from that? but what about diabetics who are on a ketogenic diet and would presumably have near-constant "keto-breath" with high levels of acetone? would it basically be unusable for them?

hiya elseye, people here are quite welcoming to foreigners, don't worry! at most they will try to overcharge you lol.

if you're looking to stay in manila, then high-end/business districts such as taguig, makati or ortigas would be better and safer. if you're planning to stay in the provinces then it depends. a place like boracay with tons of foreign tourists would be best for you, but in general people out in the boonies are very friendly and honest. do you have an idea of where you would like to go?
