Coca cola is useful for a variety of ailments. The most common is for soothing upset stomachs. Just slowly sip a glass of flat coke and it should help to alleviate nausea. It is also good for people suffering from diarrhea or a sore throat. I would say that it can also cure hiccups but, frankly, a glass of water should do the same thing, as the chemicals in coke don’t offer any special “anti-hiccup” magic.
