I saw that you told your doctor. I would have advised that because I too am dealing with high blood glucose at the moment. I have to go again in six months to have it checked out, again. It is lower than it was when I first stopped drinking but I still need to be vigilant. I hope yours works out.
On a side note, I couldn't keep it a secret from my doctor at this point anyway so I am completely honest with her. She just happened to be the doctor on call when I went in to the emergency room for detox in 2012. Imagine laying there feeling miserable and have your own doctor pull aside the curtain. Oh, hi....
