Coffee makes me me. Been drinking it since I was four. I have gone without for a total of, oh, maybe, 12 days since then?
No, I don't get any "stimulating" effects from it.
I have trouble hearing human speech or making words at all without coffee. Before the first cup in the morning, I'm on sensory overload autopilot. I used to think it was no-thought, but now I believe it to merely be total-nonverbal-thought.
I went 10 days without, once. My body felt great after a couple of days, but I barely spoke a word to anyone or listened to what anyone else was saying. Just walked around Seattle, looking at and listening to things, (and touching the icky slugs and weird rain forest plants, of course.) Seattle was not an effective place to try to quit coffee. When I had the most mindblowingly good shot of espresso I'd ever had, the words came flooding back. "That was a painful, yet curious, experiment," I mused, "yet not one I'm likely to repeat."
