My time in the Peruvian amazon was one of the best of my life. Where were you specifically. Pretty sure I saw some shots of Iquitos there. I spent my time in the Pacaya-Samaria reserve just above the confluence of the Marañon and the Ucayali. No DEET is the way to go, doesn't really slow em down and in high concentrations is pretty bad for you.
Ah Inca Kola, looks like piss tastes like bubble gum, nectar of the gods. I brought 10L back of it, all gone now though.
