I like sugar and and I love chocolate.
I eat a little sugar and I eat a fair amount of sugar-free chocolate (Asher's bars).
I work out at the gym several days a week and I stay pretty trim and fit.
And caffeine is one of the 4 major food groups.
But I eat sugar and chocolate sparingly (everyday), and I have never lost a wife or a job from drinking caffeine.
So I have no desire or plans to give up any of these pleasures.
Whatever life's other dietary or behavioural problems are, drinking is worse.
I quite chewing tobacco, dipping Kodiak and smoking cigars when I got sober.
To be quite honest, I miss them, but, mercifully, I don't miss drinking (who misses being sick, being broke, having insurmountable problems, being constantly in trouble, and losing important things and relationships?); but, I do miss chewing tobacco (when I'm on the farm) and smoking a good cigar after a good meal.
