Have you read these? I just read through about half of the first one and it's not very convincing. The severity of symptoms is extremely mild and they don't have comparisons to cessation of other drugs or habit forming activities.

It's sedating, and withdrawal of a sedative is associated with increased excitation sure. But we need to meaningfully differentiate the difficulty you have sleeping after abruptly stopping exercise or trying to sleep in the middle of the day from persistent and disabling neurochemical changes. Like the it's not clear that the irritability or whatever is separate from the withdrawal of any other pleasurable activity.

The number of people they describe having severe enough symptoms to continue use across the studies reviewed is around 3%. I suspect you'd see more impressive numbers for coffee lmao.
