I'm always a bit amazed products from this aren't more widespread. If the cost was lower (costs about $1-$2 a tablet now) I think I'd use them every day.
From the article:
> "You can eat a berry and then bite into a lemon," says Harvey. "It becomes not only sweeter, but it will be the best lemon you've tasted in your life."
If you eat a miracle berry and then snack on a whole bunch of lemon slices, they may not taste sour, but you will regret it in all kinds of ways.
Also... miracle berry + lemon doesn't actually taste particularly good. There are "sweet lemons" and "sweet limes" (low acid varieties), and they're not popular because they're bland.
