To Drink Or Not To Drink...Diet Soda

So what's your take on all the hoopla surrounding diet sodas?
Reports are saying:
It may lead to kidney problems
It may put you at risk for heart disease
It may lead to obesity
It may damage DNA
It may rot your teeth
And then there's the can itself. It's coated with endocrine disruptor bisphenol. Whatever the heck that is. It's supposed to be full of all kinds of bad juju, that can cause reproductive problems, obesity and heart issues.

What's your thoughts on this? I drink two cans of diet a day and it would be hard to give up. The only thing I can say with any certainty, if it caused obesity I would have put on the pounds years ago.
