Nice to see some pics with your story I doubt it was the malaria tablets-probably the food or ice/water in something as my stomach was dodgey most of the time I was over there as well and even immodium didn't improve it!
i think most likely the food and Lolita kept feeding me but later during the second week i think it was , i had home made ice cream at the school bulk made, proberbly made with local water which wouldnt have helped
