Diet Rite has no caffeine and no aspartame but does have citric acid (implicated possibly in some stalls), and Splenda or a reasonable facsimile. Now, Diet Dr. Pepper has no citric acid and there's a no caffeine version available, but it has aspartame.

As to the shadowy claims that diet sodas spike insulin, I'm so tempted to go get a blood glucose meter and see if there's any budge downward at all in my blood sugar after having these... I doubt it as I never feel 'weak' after having them.

Anyone ever tried this?
