They tell you in all the commercials and ads, they are the same, one just has less calories. They are wrong!
Here is a blurb from Dr Pepper’s Website:
Enjoy the surprisingly rich taste that satisfies without compromise. Diet Dr Pepper offers the same bold flavor of regular Dr Pepper minus the calories. So indulge in a more flavorful experience. Because with Diet Dr Pepper, there’s nothing diet about it.
Drinking the Diet Dr Pepper version would save you 100 calories, but it is certainly not the same taste and flavor as regular Dr Pepper. I happen to like Dr Pepper, although I don’t drink it too often. (I don’t drink soda much to begin with, unless it is caffeine free, with the exception of if I have a migraine because caffeine can help that.) I only even got the Diet Dr Pepper because I had a coupon to try it for free. And yes, just because it is free doesn’t make it good. I have now learned that Diet Dr Pepper does NOT taste the same as regular Dr Pepper. So in the future, I will just suck it up and drink the 100 calories in the Dr Pepper!
