Good for you having that all on hand. If your just drinking water you might add a pinch of salt to that at least less your getting it from something else.
Looks like your sinuses might be draining out the virus. Mint mouth wash gargle or hit as you can take it gargle.
I didn’t have much of a problem with that but used liquid zinc drops.
There’s a homeopath that drys up the sinuses called hydrastis canadensis and works pretty fast.
Looks like your going to recover fast.
Your doing good.
Remember those liquid salt tabs the military gave out. Yuck
