Sometimes I wish I could drink energy drinks, but I have a few heart problems and when I do drink them... I don't feel good at all. I can FEEL my heart beating and beating HARD. Not racing, but a slow, hard thumping beat. However, If I am just soooo tired, I can drink a half, sometimes even a whole 5-hour energy. They don't seem to affect me very much they way Monster-like drinks do. One thing I drink every morning on the way to work is V8 Fusion Energy. It's got good healthy stuff in it
