Coffee is a drug and that addiction is real. It's still debatable, but the symptoms of coffee withdrawal are a good indication of that. That being said, it also really depends on your daily coffee consumption. If your coffee dependency is very high and spread throughout the day it will affect your sleep, cause morning fog and lethargic feeling as your body is sleeping, but your brain is not getting a good night's rest and the withdrawal will be a difficult too. There was a small research done which determined how to maximize the benefit of coffee drinking by drinking it in small amount but changing the time when you drink coffee. Morning coffee is a bad habit as your cortisol levels are high, and you should drink coffee when that level drops. So between 10am - 1pm is a good time to drink your first and only cup of coffee as it stays in your system for 8-10hours, so you should adjust that timing based on the time you go to sleep. And to make the most of it, you should drink as much as you want, 2-3cups in that window. I was a morning and evening coffee guy, but I now drink between 11am-1pm, the first few days I had severe headaches by 10-11am because of the delayed coffee kick, but later it tapered out. Now I do have a coffee dependency so if I don't drink coffee I do get headaches but since that window has shifted my headaches don't start before late evening which can be managed with a short walk and trying to sleep early. Which I think is healthier than having the day ruined.
