I'm going to try a different approach instead of quitting, I need to be realistic. There are some benefits to coffee and I do benefit from it, when taken in moderation.
I will be going down to 1 cup a day and I'm strictly having this only 2 hours after waking. This is to prevent caffeine messing with my natural cortisol / waking up process. I have found from past experience delaying the first cup of coffee is hugely beneficial. When I have had a coffee first thing on an empty stomach, horrible.
So this approach was fine to begin with, it kept my coffee consumption in check, for a while. I started to get a really big crash between 3-5pm everyday, so I added in another caffeinated drink around lunch time. All that did was push the crash a little later in the day but also increased how much I was drinking.
After a while I noticed things getting worse - heart rate was always up, chest felt a bit tight, mind was always racing and needed something to do/solve. My mood was inconsistent and I got stressed more easily. I got tired of having to manage my caffeine "dose" to manage how I functioned.
3 weeks ago I started to taper off how much I drank, then gave my wife the warning that on 22nd December I was completely off. It's been a bit tough, but with a 20 minute power nap to help with the drowsiness and brain fog, I pushed through.
There's been a few days now where I've not needed a nap and I'm starting to feel really good. Calmer, less irritable, heart rate/blood pressure lower, more stable energy and much better sleep. I now feel awake in the morning, and actually feel more awake in general. I'm no longer jacked up on stimulants/adrenaline, which is no way to live.
I'm aware I've quit before and falling back into bad habits, I really hope I can kick this one for good this time.
I've been drinking peppermint tea, decaf tea and diet caffeine free coke which does help.
