I had this on mind, for example, because a few weeks ago a co-worker had to leave work early one day because she had a terrible migraine that wouldn't go away. She was out of the office for the next few days and even went to a doctor because it just would not subside. What she eventually discovered is that she accidentally bought a decaf coffee. When she switched back to regular, the migraine completely subsided and she has been fine since.
Her experience really struck me. It's not really a subject I have ever thought about before, but I wonder how prevalent that level of addiction to caffeine really is.
Headaches are a thing if you quit too fast but they usually only last a few days. For me the worst part is losing the rituals of coffee. It's hard to give up years of routine.

Give them a fucking break.
