Interestingly I've always found that caffeine doesn't do a whole lot to me. If I'm tired, I'm still just as tired afterwards. I only really drink it for the taste
I've found in the past that one to two days actually does help me reset (I just spend most of it sleeping) - I don't actually have that much coffee compared to most people, only one cup a day and always before 12 - but I wouldn't mind trying a whole week. I'd need a med cert though lol.
Fair enough. About ten years ago I tried going cold turkey when I was averaging i guess around 10-15 standard cups a day... First three days were brutal headaches and agitation etc. Then the next 2 weeks was constant brain fog. I couldn't work. Couldn't hold a train of thought. Gave up the attempt when I still couldn't work after those two weeks. Helped me dramatically reduce how much I was consuming at least.
I think I relative get off lightly and don't get any adverse effects if I stop drinking coffee.
I can definitely get buzzed with a coffee high if it's really strong and fresh as opposed to instant coffee but I've never had withdrawal effects touch wood
