Uh, yes and no. I have gone on and off caffeine for years. The withdrawal is mild--nothing a couple of ibuprofen and staying hydrated can't mitigate. It's not heroin! After say 48-72 hours, you're caffeine free. I drink coffee to stay sharp while coding, but like I said, I have quit it for long periods of time due to sleep issues and things. I now mostly just drink decaf for coding (note: decaf is not "non-caf"). I should add, I've never been addicted to anything ever--for whatever reason, I can just walk away and never want <fill in the blank> again. For others, psychological addiction can be tough to get over.
