My 19 yr old son was admitted to the hospital on Friday. His heart afib, His organs were failing as well. He was drinking very high caffeinated soda's as well as energy drinks daily allot of caffeine, Everyone told him to stop drinking so many. All he did was stay in his room playing video games or on the pc from 11 am til 5 am the next day. He ate well, rarely drank any water, then a month ago, he stopped eating, vomited anything he drank or ate. Then he started drinking a gal of water a day, or chewing on gum or candy. Was burping allot, then his heart was beating fast so we took him in. Now I'm told he has an enlarged heart. Where did this come from? He's the healthiest one in the family. He's had maybe three colds since birth. Could all the caffeine and other ingredients do this to him?
