No, not the mood-enhancing kind. The health ones instead. I thought that I was getting a stomach of steel due to the fact that I hadn't been ill since I have been in Thailand (70% of travellers experience illness in their first two wks of being in a country), but no. Today I was reading my antimalarial fact sheet, and duoxycycline, the anti-malarial I am taking, is also used to prevent traveller's diarrheoa, and in fact, I have just been protected by modern medicine. Bring on the dodgy fish!
