Yeah, it's a bit weird. I have no withdrawal or rebound effects at all. If for whatever reason I suddenly go 3-4 days without coffee, I have no headaches or other obvious poor effects, apart from the fact that I may miss the enjoyment.
My daughter gets really bad headaches if she goes a couple of days without it.
There's definitely a tolerance effect though. Several periods in the past I have gone long intervals without coffee. And then, when I drank that first cup it felt like a shot of amphetamine. Wow!
