Upon closer examination I found that the little white balls were not at all what I expected. They were all the exact same size and shape as well as firmness. It appears that they are balls from extended release medication! of all things! I take my medication first thing in the morning with my breakfast....then about 2-3 hours later I take a shake. So I am sure if the balls are from current medication....or if they have been looming in there for a while.
