Since we're throwing around anecdotes. I quit coffee for two years to help with anxiety. It did help with that, but there were zero other benefits, and the significant downside of not having something tasty to sip on.
After the first few weeks I didn't feel groggy in the morning without the coffee, but I definitely wasn't feeling any more rested. It didn't help me get to sleep any easier either. It also didn't help me get going in the morning any faster.
It did have some benefit to anxiety, but after I improved the original source of that anxiety (work related) I eventually went back to having coffee again simply because I really enjoy the flavour.
