Caffeine withdrawal is very very unpleasant. If it's a daily habit and you abruptly cease consumption (aka "cold turkey") you're going to be in hell for at least a day. Usually more. Occasionally you'll hear people talk about quitting this way with zero withdrawal. They may or may not be telling the truth. But I suppose outliers always exist. Definitely not the norm though. I know a lot of people who say they that can't function with caffeine Yeah, because of the withdrawal. They could function fine without it, once they got past the withdrawal. Of course, there's really no need to suffer painful withdrawal. It's pretty easy (at least physically) to just taper it down to 0mg per day over the course of ~5-7 days.
