Diet pepsi is sooo good. The first time you drink it you may think ’’ewwwww’’ but after a while you begin to like it and before you know it instead of asking for regualr pepsi you will be asking for DIET pepsi. If you want something a little bit different then regualr pepsi than BUY DIET PEPSI! I think diet pepsi is sweeter than regular pepsi!60 Diet products contain Phenyalanine, which people SAY cause cancer, BUT if you do a little bit of reasearch you will find that Phenyalanine is an Ammino Acid, which an Ammino Acid is the bulding block of protein, and protein is good!!! SO IN NO WAY DIET PRODUCRS CAUSE cancer. DRINK AWAY!! :)
