title_body: Am I psychologically addicted to coffee?
upvoted_answer: Studies show that caffeine withdrawal is more of a psychological than a biochemical phenomenon. For example, if we know that stopping the consumption of caffeine leads to headaches, they will happen, because waiting provokes a reaction. This, in particular, is evidenced by a review of the 2004 journal Psychopharmacology, in the preparation of which scientists analyzed more than 50 articles from medical literature on a given topic.
