I drink coffee out of necessity, not enjoyment. The necessity is exacerbated by the intake of psychothropic drugs. Since many people on this forum simultaneously work outside the home and take psych meds, the need for caffeine is especially pronounced. I have a thread about that, and from the multitude of responses and approaches you can gauge that it is not a fringe problem. A blanket, unrealistic prohibition is not welcome in such circumstances. As for the interplay between caffeine and metabolic disorders, I have never heard of that even though I am fairly read up on diabetes, and stand ready to be educated, therefore. Going back to the beginning, I am very glad you realize that loss of enjoyment is a consideration of great importance before issuing lifestyle-changing recommendation.
