I'm pretty sure once they show the list of side effects, most everyone chooses Malarone. Still an open question why they even bother to offer Mefloquine given the side effects and potential for long term damage.

Good old DND. Arm people to the teeth, deploy them to a raging shith@le with national or international media watching and give them meds with known neurological side effects. What could go wrong?

Seems legit ;)
