I didn't read the entire article, but also heard this on the news just this morning. I can't drink caffeine. I used to drink 1 Big Red (cola) daily because I love them. Just from that 1 daily cola, I had really really bad fibrocystic breasts which made my left breast hurt really bad during PMS type and I developed palpitations. I stopped drinking them, and I no longer have the pain, feel the knots anymore, and no more palpitations. I do eat a piece of chocolate daily which also contains caffeine, but this doesn't bother me, probably because it is such a small piece.
