Related: #407495 (lots of interesting comments there, mostly on the benefits of stopping coffee).
Here I'd like to inquire about your personal experiences of getting back to coffee after stopping it. My main motivation is that (i) I was not too sensitive to coffee to begin with, so it never really affected the quality of my sleep and (ii) my metabolism seems to have slowed down.
Of course, the latter is hard to quantify objectively, but my stool is much less frequent in time as well as in volume, and, while I used to lose weight easily when eating/drinking less, now under similar conditions, I can't seem to lose weight. This observation agrees roughly with the time I stopped drinking. Of course, there could be other factors at play.
As to the former, I wake up much more frequently at night than I used to when I was still drinking coffee. I maybe need a little bit less sleep to feel rested, so that's the one benefit I might be throwing away by picking up coffee again.
Supposed benefits according to science of drinking coffee are not to be discarded too (reduced Type 2 Diabetes, better liver health, heart health, cancer and stroke reductions, improved gut health, reduced risk of neurodegenerative diseases, etc)
So, what are the benefits of drinking coffee for you? Do they outweigh the disadvantages? Can you convince me not to drink that cup of coffee I'm about to pour myself?
