"As a type 2 I was under control & coke would be a regular drink at dinner for me without causing much of a spike. However over the course of 2 weeks I spiked so high I had to go on insulin & after a week just looking at the Coka Cola in my fridge I bought some Coke Zero, I was pleasantly surprised with the taste, though it is not close to the original it does have a pleasant taste to drink unlike diet.. Wont touch diet coke.."

Coke Zero tastes great and the “best by” date is 1.5 months out, so there’s no hurry to consume the product. I enjoy drinking one in the morning and then I drink sparkling water the rest of the day.What Customers Talk About
