Iced Tea, then Stewart's Diet Root-beer.
last resort Diet Pepsi
Worst drink ever: Mountain Dew/Code Red or anything with Prune Juice or Cherries ( Dr. Pepper).
It appears you are my opposite IL (The Good Captain Kirk vs Bad Captain Kirk of Axis and Allies). I am convinced God maid Dr. Pepper for me, knowing I would arrive in 1973.
Although I worked 7 years for Pepsi, Coke does taste better. (Normally)
"Throwback" Pepsi is nice though. (Uses real sugar instead of corn syrup: currently available in the St. Louis Market for a limited time)
