The problem is people get addicted to it. So maybe they think they can break the addiction by drinking a substitute like this, but since they're addicted to caffeine & sugar, they're just teasing their dopamine receptors & will keep drinking these types of things in a neverending pursuit of sugar & caffeine.
Until they ever might WAKE UP & REALIZE WHAT THEY'RE DOING TO THEMSELVES,
and begin the battle to fight the addiction and learn how good it feels to eat clean, drink clean.
Water is the nectar of life, y'all.
