I was drinking 4 cans of coke a day. I think part of the reason is that I live in a REALLY miserably hot climate, so that's partially what creates the temptation.
Also, I gained about 8 pounds over the past few months.
So yea, I tried to ditch the coke, but Coke Light (Diet Coke) tasted like crap to me.
That's when I discovered Coke Zero, which tastes so amazing. It has all the taste of coke without the sugar.
Anyway, I've lost 4 pounds in the past few weeks since switching. Yay.
