They don't put phen-phen in diet soda.
I love the Dietrite as it's the only soda sweetened with Splenda.
You might hate diet soda but consider how many calories you'd lose by giving up a 6 pepsi a day habit. 6 cans of Pepsi has 900 calories. If you multiply that by 365 days that's 328,500 or 93 pounds worth of calories. Yes, you'd lose 93 pounds worth of calories in ONE YEAR if you give up that Pepsi and go with a diet drink or water!!
