I am unexpectedly happier without coffee. Despite being such a pleasure to drink coffee, or at least caffeine, has been a barrier between me and happiness.
I think the most powerful effect has been on the improvement in the quality of my sleep. I need much less sleep to be satisfied, and I don’t have to drag myself out of bed.
A second effect is that I no longer have to fear headaches. I get the most dreadful headaches from caffeine withdrawal. Not drinking coffee frees me from the worry having to keep my caffeine topped up.
