Use 1 tablespoon of vinegar in a glass of water, about 80ml and drink it. No need to buy expensive stuff, Asda & Morrisons' both do one in a plastic bottler for under £1!
Apple Cider Vinegar in water works a treat! I was feeling so yuck for about 6-7 months with no relief and only given chemical nasal sprays by my GP, I saw this advice and took it, coupled with a sea water nasal spray. This remedy is great. I am still a bit icky at times so am going to try the Turmeric.
