“While I was hesitant to try Focus at first because it has caffeine in it and I have a caffeine free diet for many years I decided to try it and just take a few sips and see how it made me feel, the caffeine must be very low because I didn't feel any different but what I did notice was how DELICIOUS the FLAVOR WAS! Since trying it Focus has become one of my favorite flavors. It's extremely refreshing and light and I have a specific system of how I choose my flavors each time I need a refill so I'm always super excited when I see my pick is Focus . If you haven't tried this flavor I can't see a reason why you wouldn't love it!”
