I know this is completely the wrong thing to do but when I've had food stuck before it was my first instinct to reach for a sip of water to try to wash it through.... Trust me, this makes it 10 times worse because your little pouch is already blocked so putting fluids in it only makes it more full... I have done this twice hoping that it would wash the food through but both times it has just made me sick! That'll teach me!! Lol xx
