I am also severely addicted to caffeine. I can't win all of the battles. But I can empathize with you. I just try to realize that it has negative effects on my sleep. But then I get into non-reasoning mode then I drink a cup late at night (of coffee that is). I realize this may not be of much help. But try to release the temptation of caffeine and maybe it'll help. That's what I still struggle with regarding any drug, mostly alcohol and caffeine though. They're just so tempting to use.
