Would really appreciate somebody looking at Sam's spreadsheet. His BG has been really high so I have tried to slowly up his dose. Was getting scared of the high numbers and we seemed to be stuck there. But now he seems to be on such a whack more ProZinc than when things were more settled? I totally understand the importance of making very small changes. But against that I am off work until next Tuesday so can test him through the day if he does need changes to his dose. Thanks for any advice.
