The St. Petersburg, Fla., couple refuses to drink the caffeinated beverage, which they say is bad for their health. Mike and Trina swear by their coffee. He enjoys a fine espresso grind, which is "on the cold side"; she prefers a "saturated blend" that is "warm and thicker."
"I started the whole debacle," Trina, who did not want to reveal her last name, told ABCNews.com. "Then it took on a life of its own. I twice tried to stop and felt worse, so I do this every day and as much as I can. But it's very time-consuming."
