She said take 1000mg of Amoxicillin twice daily and and the juice of two coconuts

So the other night I was laying in a Lao hospital bed on a Sunday night watching a lizard eat insects off the wall near the light and waiting for the results of a bood test for Malaria and Dengue Fever. As luck would have it I had neither and my 8 day headache and 2 day fever were chalked up to a random infection and the muscle spasms in my legs to dehydration [partially from the aftermath of a dodgy tuna sandwich] and low potassium from sweating while hiking. 270,000 kip ($40 US) later [it being Sunday night and all so double the regular rate] and the solution was evident - a prescription for Amoxicillan, 5 packets of World Health Organization hydration salts and direction from the doctor to drink the juice of two coconuts every day as cocunuts are high in potassium. Problem solved.
