PAWS (Post Acute Withdrawal Symptoms) can last for months or even up to a year or more with caffeine. Please don't give up and start drinking it again as you will end up in the same situation that made you want to quit in the first place. What makes you feel good about yourself is consistent action towards a set of goals and achieving them.

This isn't to say I don't know what you're feeling. I ate 10 pieces of dark chocolate without even thinking about the caffeine content, and by the time I realized what I'd done, I was already feeling "normal" again. That's the exact reason we're all here to quit. Not needing caffeine to feel like our normal selves.
