Sugar is the third most addictive substance known to man. I'm studying to be a registered dietitian. I can confirm sugar is, in fact, the devil to your health. Inflammation causes disease, sugar causes inflammation. If you chose to use, you must time it correctly and use it for the instant fuel it is, immediately preceding a full workout. Diabetics are not the only people who get blood sugar spikes either, but frequently spiking your blood sugar will make you a diabetic. Insulin resistance is easy to develop and much harder to remedy.
Now, I know that sounds like a lecture. I don't mean to be condescending, it's just the science and I am a student. Obviously you can have a sparkling apple juice for new years, but if you're regularly buying juice to drink that's just as bad for as regularly drinking soda. And carbonated drinks cause bone density loss and mess with calcium uptake, that's part of the whole "Mountain dew mouth" issue.
