any different, in fact, I think I felt worse since I wasn't getting that caffeine stimulation once a day. However, I was never drinking a lot of it. Like an 8 ounce can once a day. 25mg. I think people would be a lot better off if they just cut down on the amount and not worried about having to quit and then wanting it again. Seriously, an 8 ounce can is enough. That's where I'm at now.
