My weakness is soda. I just love the taste of Pepsi, but I know it's killing me on losing weight. I've got Mio Energy drops for caffeine, but still have no willpower knowing sodas are in the house (can't get rid of them, my granddad drinks them).
Im assuming your talking about regular Pepsi and not diet? Have you tried Pepsi Max? I taste a lot like regular and has twice the caffeine as diet.
I hate diet drinks but can do Pepsi Max and love Coke Zero.
