I have quit caffeine in the past so I know it can be done, but I would sure hate to have to quit coffee. I like strong black coffee, regular and decaf, and it is one of my last remaining pleasure “foods.” For those times when I have a psychological craving to treat myself, going to a coffee shop or making a fresh cup at home usually satisfies that without any food intake.
If I ever get into a prolonged stall I may give it a shot but that’ll be one of my last resorts.
