I like this saying a lot, but I have found the opposite by experience. I stopped drinking coffee recently, and frankly, I found that coffee didn't add much positives to me, aside from the feeling of looking forward to drug myself. The evaluation of its effects after ingestion is bleak - my mood improved after 10 minutes for like 30-60 mins, then I was back to my normal feelings. I sweat a lot more, was more jittery, and much more irritable throughout my entire rest of the day. Which I didn't even know about, since I have been taking caffeine daily for 20+ years now.
