Hi Tsar. I stopped doing that. All that sugar is not good for anyone. I am willing to bet my nutritionist would tell me not to consume all 8 drinks that come in a pack at a time. Those little yogurt drink containers I was referring to are less than one pint full each. They are about the size of your thumb.
The 8-packs look something like this:
If I want yogurt I can simply buy plain yogurt and if I want mix it with unsweetened applesauce.
You have to be careful what kind of berries you consume too. Blueberries and cranberries are full of antioxidants, which are supposed to be good for energy, but these berries are high in acid.
