Thanks for the tip about Diet Coke! My mother does get her meds through the feeding tube. The doctor tries to prescribe liquid meds much as possible, but some only are available in pill form. We use a mortar and pestel to crush them as fine as possible, then dissolve them in warm water. We flush the tube with water immediately afterward, and so far have not had much of a problem with clogging. If we do need to switch liquid nourishment, though, and the clogging becomes a problem we will know what to do!
