Just don't drink the tap water down there. I did and was so sick I could barely crawl to the bathroom and back to bed for about a week. Finally someone suggested I try eating some raw garlic. At the time I had not developed a taste for the stuff and detested the thought. I didn't have the $ visit a doctor or buy any of them fancy remedies. Playing on the street was what I was doing for survival back then. Since I had become sick I wasn't able to do anything but suffer in bed. So I chewed up and choked down about four raw cloves, with some filtered water, and in about an hour or two I was miraculously cured of the ailment that had plagued me. Since then I've sworn by it instead of at it.
