I've had a really bad cough and cold for the last 4 weeks and i would wake up at night, coughing and my nose would be running( disgusting, i know). one night i was hungry so i went and had a toast with butter on it and a paracetamol, i didn't cough for the rest of that night and it has worked. Now, before going to bed, i have a teaspoon of butter that i suck on and so it melts in my mouth and a paracetamol for my cold and it has worked. i recommend this for people that wake up from their sleep in a fit of coughing. i hope this works for you guys!
