My wife and I are both Coke people. However, I will drink a Pepsi if Coke isn't served. She will not. I would never buy Pepsi over Coke. No way. No how.
I swear, Coke a Cola is one of the few food products I crave on a regular basis. I remember there being times I would wake up at 2 or 3 am and then check the fridge for a Coke. If I was out, a drive to 7-11 was not uncommon.
I could chug the heck out of Coke as well. It's impressive.
