You seem like you’re already doing everything you can to treat your symptoms. As Kolanaki said, there is no cure for the common cold. I’d continue getting as much rest as you can before your vacation. My colds usually take atleast 7-10 days to fully go away and that’s with proper rest. Sometimes I’ve gotten lucky and only had symptoms for a few days. If you have a sore throat, throat coat tea helps as well.
Shit—to leave the house in general 🤣🤣 I’ll do anything to avoid that awkward conversation
