I have been drinking Dr Pepper for 40 years, but recently it has changed. The soda is now FLAT. That great fizz and strength is gone (I used to hear it in the can, even a while after opening)! I can now handle maybe 2 drinks out of the can and then have to throw it out. I thought it was a bad batch, but I've tried bottles, cans, different sizes, but all the same; it has gone FLAT. I'm so disappointed after years of being a loyal customer. PLEASE change it back! User's recommendation: It's not what it used to be.
