Does anyone else have a problem with coffee raising their bg? I can't function when I get up until I've had a couple of cups of weak coffee, no sugar, small amount of milk. This morning my bg was 5.7, half an hour later and two cups of coffee later it had risen to 8.9, that's okay as I can correct with insulin when eating my breakfast shortly after, but I'm not happy that maybe I might have to forgo my mid morning and afternoon coffee.
