Get yourself liquid day nurse, night nurse, covonia throat spray, lemons and honey.
During the day, take the day nurse. Gargle every so often with warm salted water. Drink a few cups throughout the day of hot water with a slice of lemon in it and heaping teaspoon of honey.
Tonight, switch to night nurse, before bed, warm salted water gargle, tea with honey and lemon, throat spray before bed. Make sure your head is elevated when sleeping. If coughing gets bad in the night, do the gargle, lemon and honey tea, then throat spray.
The gargle helps clear out anything in your throat (mucus) and works on any infection. Day/night nurse not only has the paracetamol in it, but also works on drying out what’s causing you to cough (post nasal drip?)
Throat spray really numbs yourvthroat. Helps stop the cough.
Best of luck. I had this recently for two weeks. one night I coughed so bad that I burst a blood vessel in my eye!
