Muscle Milk Zero Sugar

Hello, I hope you peeps are doing okay! I'm so thankful & happy that there's a page like this. It's helped a lot to read advice from here. I'm male, 5'8", 29, and I was 167lbs. Now i'm at 158 with a goal of 150lbs. I work full time and go to school full time. I developed prediabetes from the convenience of fast food and drinking energy drinks a lot. My wake up call was a moment at night where I woke up believing I was having a heart attack. Now I've been going strong with my diet for a month (whole grains, whole wheat, kale + other greens, brown rice, a lot of eggs, lean meats, occasional apples, blue berries, etc. no sugar/caffeine. counting carbs.) and I am training for a climbing competition next month. I do, however, miss desserts. (I promised myself I'd consume something healthily fun once a month.) My gym sells Choc Muscle Milk Zero Sugar, and a bakery near me sells keto cookies.

Anyway:

TL:DR Have any of y'all drank this during your journey? Is it safe? Also, what diet friendly desserty/snacky things do you reward yourself with?! I'd love suggestions.
