Diet Pepsi is my choice of carbonated beverages. I used to drink a lot more than I do now. Now I drink more coffee and water. I have always preferred Pepsi over Coke. The only time that I drank Coke was when Vanilla Coke first came out. After drinking it for a couple of months, I started breaking out in hives and was advised to stop drinking it. So I did and just went back to Diet Pepsi. I have tried Vanilla Pepsi (is it still available?) but I didn't drink it very much. I prefer bottles and I could only find it in cans. So regular Diet Pepsi it is!
