try salt and water together everyday once in the morning and once at night it helps me all the time and also you can try warm tea that helps as well if you don't gargle the water everyday it wont get better and it only takes seconds to really works for me I've been doing this for 6 months everyday i just stopped gargling 4 days ago and my throat feels 10 times better no more mucus or anything. you can also gargle mouthwash and hydrogen peroxide i prefer the salt and water and the hydrogen peroxide because it breaks my mucus up and pushes out completely it works for me I hope it works for you!
