Best cold remedies?? Of course I get sick on NYE

For 3 days now I've had a cold coming on, it hasn't worsened in severity really but I had a sore throat the first two days and now I'm just sneezy, have a tickly cough, am a bit congested, and overall don't feel the best. I have some plans for tonight and I really don't wanna miss them!! I've been drinking a lot of tea with honey and a lot of vitamin C (natural and supplement forms). I don't like taking medicine (especially NyQuil or DayQuil). Are there any other remedies you guys would suggest?? I don't wanna ring in the new year feeling like a sack of 💩 :(
