Suggest Remedy For Dryness Of Throat

I most probably have a virus or something (mild cough,some headache and sometimes nausia,started 3 days ago). These symptoms don't affect me much,what it does is continuous swalling of saliva due to the fact that I feel my throat very dry (and sometimes like I have something in my throat). What can I do to make it stop,because I cannot sleep at night? I know it will go away with the virus,but I need a good night sleep. I am male,29 years old.
