Oh it's GREAT ... especially first thing in the morning as a pick-me-up or even to recover from a hangover. I've heard it has something to do with the combination of lemon-lime and pineapple flavors that actually boost energy levels in a person. It really works too ... I always feel better within a couple of hours after I drink this when I need relief.
Mix 1 cup Pineapple Juice (I like the Dole brand)
and one-fourth cup of Sierra Mist (in a 12 oz. glass)
**the Sierra Mist MUST be room-temperature ... the pineapple juice can be refrigerated**
(Also FYI ... do not try 7-Up, Sprite or generic Lemon-Lime sodas as they have way more sugar than Sierra Mist ... believe me, it's the combination that 'makes a difference')
