Richard L,
I've controlled my type 2 diabetis (hey...no meds), and as part of it I switched completely to black coffee. Before that I would drink black coffee at home, sometimes with a little sugar, and have cream and sugar when out...not sure why, probably because coffee out can be hit or miss and the sweetner and cream makes it safer.
But now, I drink black all the time.
It doesn't take that long to get used to, AND, I find that I actually enjoy good coffee more.
There is one generic I won't do, however. I only like Heinz Ketchup....no generic will do.
TJR
