I have heard many times from various sources that liberally covering the soles of the feet with Vicks (and wearing socks!) has a magical effect and stops the coughing - just like that! Have been a bit , but am now desperate and thinking about a hotel room just for me, as it's 2 dcs and dh with man flu - aargh!
Anyway, ds2 has been in bed for 1.5 hours, fully Vicks'd up, and so far, silence!!
