Am I the only one?

I (58m) have been a daily (give or take) Kraken Black Rum drinker since 2012. My preferred mix is 4oz Kraken and 12oz Caffeine Free Diet Pepsi. (yes, I have other issues) I mix my batches in a 2-cup Pyrex measuring cup and usually have 2-3 rounds a night. I absolutely love the flavor of the two. Yes, I’d prefer not to drink diet, but I don’t need the extra calories. Am I the only one?
