I have a bit of info that may help you out as well. My wife is diabetic as well, I also thought that my spritz was going to have to change. I use 8 oz 100% apple juice, 6 oz Jack Daniels, 4 oz water, and 2 oz cider vinegar. After discussing this with her DR and the dietitian they concluded that the amount of sugars/ carbs you would get from this was very minimal, and it would be OK for her. This was there reasoning. The apple juice is 100% juice no added sweeteners so the only sugar in it is natural 4 oz of apple juice is 1 serving. The alcohol in the Jack Daniels will evaporate so the sugars/ carbs there are very little. there is no sugars/ carbs in the water or vinegar. I have been smoking PP, ribs, brisket, and various other items using this spritz. As long as she doesn't over eat it or add bottled BBQ sauce, her blood sugars do not rise more then normal. Her A1c levels have been good so far so we see no need to change any thing. The DR and dietitian did recommend she not eat allot of fatty foods, but as long as she eats in moderation all is good.
BTW it appears you have TBS coming from your smoker, looks good to me
