Well, it would explain alot with me.

During my teenage years and into my twenties I was known to drink 2 liters of Coca-Cola a day! (gulp!). Yes, I had a serious addition....

Now I'll have maybe one 20oz bottle a day...

But, isn't caffine suppose to be protective? I would hope maybe they cancelled each other out!

Oh well, not much I can do now...but I will think about giving up the habit completely...
