Some of them do taste foul. I have twice taken medicines back to the chemist and asked for one with sugar rather than sweetener cos quite frankly, when my son is ill, I just want him to take the medicine, I don't care about it being sugar free. I also took one back to the nurse at the surgery for her to look at when my son had really bad tonsilitis as it was so thick with bits in it resembled artex. She said it wasn't dissolved proerly and shook it, but once she realised it wasn't going to dissolve any more (obviously i had tried shaking it before taking it in to her!), she prescribed a different sort. So I would suggest going back to the chemist/doctor and explaining to them. Also, a spoonful of butter first is meant to work as it coats the tastebuds with grease for a minute or two.
