I'm with Brad. Unless you have some specific health issue, I don't think there's any reason to give up caffeine completely. Ditch the soda immediately. Even diet soda has vaguely negative health effects. You might think about switching to tea, which has less caffeine and is very beneficial to your health.
I love coffee. It tastes like a bit of heaven, puts me totally on point, and it doesn't keep me awake at night. Also like tea, but I like something in the morning that makes the hair on your neck stand on end. And they told me I shouldn't bring Scotch to work anymore
