I cut back on caffeine a lot but not entirely, after quitting alcohol I needed something to keep me going through the day at work, but then realised I was drinking far too much.
So what I do now is still have my 2 black coffees in the morning (the first of which is in my hand at this moment
) and then I switch to decaf after that until I get home, my evenings are now coffee free and instead drink green/white teas.
On the whole my caffeine consumption is down but not cut out completely, everything in moderation.
