Day nurse and night nurse helped me mostly. Don't buy the tablets, get the separate syrups so that you can alter the dose to suit you, which ends up being cheaper. Also Boot's mucous cough relief, Benylin do a more expensive one. Sudofed capsules are great, but very expensive. However their mucous relief nasal spray is cheaper that Pirinase, and very good. Excellent for a quick squirt when the syrups are starting to wear off.
In the evenings before I went to bed I sucked an ice lolly, to calm my throat.
I found out all this because my cough from last winter simply never went away, so I neded up with a throat infection, a chest infection (still lingering) and a sinus infection. Antibiotics didn't work because I was immune to all the ones they started off trying out on me. I'm still left with a cough in the early morning and late evening, the above things are what worked best for me out of many trials and errors.
