I started low-carbing a few weeks ago, and at the same time gave up alcohol. My BG levels reduced dramatically, and for the first time I found myself within normal levels. Last weekend I started drinking alcohol again - gin and low calorie tonic, and white wine, and since then my BG levels have increased, going as high as 14, with no other change in diet. I understood that there were no carbs in a G&T, or in white wine. What could have happened?
