Yeah that is interesting... I just don't get a buzz from coffee, and yeah definitely drink it while relaxing, and enjoy coffee for coffee. That being said, if I have coffee anytime past 5:30pm I tend to struggle to sleep (yep, 5:30pm for some reason hehe). I used to drink at least 3 double shots a day and felt the same, but then if all of a sudden I don't drink coffee one day, I will feel quite tired and headachey. And I've gotten incredibly bad headaches at some breaks... I'm now planning little phases of a couple of days of no coffee, just to reset things anyway hehe. And wean myself off slower rather than cold turkey. But yeah, I don't drink it for that purpose (as a drug/performance enchancer/relaxer)
