maybe too late to quit?

My understanding is that addiction to caffeine is pretty quick to break, and withdrawals usually last no more than a day. It's not like smoking or alcohol where there's strong physical dependence.

And it's interesting that you're getting such those symptoms with only a half a cup of coffee and a half glass of coke periodically. That doesn't sound like a ton of caffeine, and my understanding is that there are only concerns with >100mg or so of caffeine (obviously varies per person). Coffee is something like 60-80mg per 8oz, and soda is something like 20mg, so depending on what "half a cup" means for you, you're at or below 100mg.

So I wonder if there's something else going on that you should consult a doctor about. Skipping caffeine for a day or two should be enough, so maybe give that a shot.
