I would give diet coke a 5 star if it wasn't bad for your health. I am a diet come addict, it's actually a problem. Once you go diet you don't go back to regular coke. You do not get that nasty sugar coating your mouth when you drink Diet coke, like you do when you drink regular Coke.

I prefer "fountain diet coke" the BEST is from McDonalds (they've even written articles on why McDonalds has the best soft drinks)

Packaging matters, Diet Coke in the bottle is the worst- in my opinion (and believe me, I'm an expert haha) Ice-cold cans are my second favorite to fresh fountain diet coke.

Diet Coke is much better than Diet Pepsi!

Life blood. Essence. I might actually die without this. I hate water. I hate regular sodas. I grew up drinking this. It's refreshing, great for drinking with heavy greasy foods. Thankfully no sugar or calories considering I drink 2 or 3 of the 16.9oz daily. I can't survive without the caffeine. I take it everywhere I go incase they dont have any.

The only diet soda I will drink! I am not a Pepsi lover and never will be. I have been drinking Diet Coke religiously for about eight years and so have a lot of friends of mine. There are other sodas I love but this is 100% my favorite diet soda because of the flavors and how it doesn’t have too much carbonation. Nothing beats Diet Coke especially when you get a fresh one from McDonalds.

If you know me, you know i drink at least 3 diet cokes a day. I absolutely love this drink. I don’t like to drink my calories so this is a great drink to quench your carbonation needs while also saving your calories. This DOES have caffeine so just because it’s zero calories doesn’t mean it doesn’t have caffeine so i would recommend not drinking this late at night. But like i said i love this drinks it’s easily accessible and relatively cheap. My drink of choice FOR SURE.

I love Diet Coke well I actually love CocaCola brand Diet Coke. I will not touch the others. There is no comparison. I mostly drink Coca-Cola classic but; sometimes I get the urge for the Diet Coke it just has a taste that gets me. It's so fizzy and when I have Subway I have to have my Diet Coke with it. It is typically pretty cheap I get it for around $1. Sometimes a 2 liter is a bit more but: it is what I mostly buy. I try not to buy the 20oz bottles because I feel like it is just a gimmick. Why buy a 20oz for $1.68 when I can buy a 2 liter for $1 or a little more. Diet Coke is the best diet drink out there.

Hi, my name is Karin and I'm addicted to Diet Coke! I have been trying to lose weight and I only drink one carbonated beverage a day and so it has to be something amazing. It tastes like regular coke, I taste no difference at all and it has no sugar and it's just yummy

I have waited my entire life to write this review. Me, the true Diet Coke Head. I drink it all day. My car is full to them brim with Diet Coke cans. I truly cannot get enough. No other soda could ever compare. And zero calories! God is good.

Diet Coke is my go to drink. After not having one for a few days and taking a sip everything seems right. Perfect amount of carbonation. Tastes much better than any other diet drinks I have had. Would recommend to all my friends.

🙌🏻🙌🏻🙌🏻 Thank the Lord for Diet Coke. I know the ingredients are controversial but this is my go to drink for every occasion. It’s not overly sweet but it’s not flat tasting or watered down. Definitely my all time favorite drink.

Is diet coke better than regular coke? (Tasting?) I don't drink pop, so I wouldn't know.
