If you love your health and yourself please dont drink any kind of drinks like these.
But its upon yourself. I dont like its taste its pretty average, I think any fruit juice is much tastier and healthier.
They cost you for their packaging and advertising.
1 liter will cost you around Rs60, which contains carbonated water with added sugar and nothing healthful. Milk is way cheaper in comparison to that.
Prefer home made drinks, fruit juice if you are health conscious for rest Happy Pepsi/Coke.
