I started drinking Coca-Cola again in the Summer (I had not had it in many years) and found it almost like a miracle drink when doing hard physical work outside in the sun. I noticed that I was getting some smelly flatulence shortly after drinking it though so I gave it up. I doubt that I will be able to drink it again but just wondered what is in it that would cause this problem and also wondered if there is another drink with similar benefits but without the flatulence causing ingredient?
