Like "Humm? Maybe its the caffine some how? I'm really not sure just taking a guess? Maybe ask your doc and see what he has to say? Like I said it seems to be the caffine? If stress can increase the blood sugar as we know it can, then maybe the caffine is acting like stress somehow in the body? Maybe increasing blood pressure ect? There's a thought? If I had to guess, that makes since to me? So the caffine is making the body seem like its stressed then there making the blood sugar higher? Its a possiablity? "
