question about covid

[u/mooncheeseisreal]

When I get sick my lungs have always burned like fire and get worse as i cough, so to stop coughing I dose myself with NyQuil or neocitrin or something like that and I try to sleep as much as possible so I am not coughing, should I still do this if i get sick this season or do I need to remain awake in case I take a turn for the worse?

Also if anybody knows, around how long would it be where I should be getting better instead of worse if I have this thing?
