I gave up recreational pharmaceuticals and "the herb"... and finally I gave up eating the foods I love ... but I have drawn a line in the sand on this issue ... You Shall Not Take My Caffeine From Me! but seriously... as with all things diabetic ... YMMV I get up every morning to fasting blood glucose readings of 85-95. I drink 3-4 14 oz mugs of coffee and don't eat my first meal of the day until about 1 pm, by which time my BGL has dropped 4-5 points ... so ... as I said ... YMMV namaste Steve"
