Quick home remedies for cold sores?

So this morning I woke up with a cold sore. Today is thursday, and I need it to be gone by Monday morning. (I’m going to be on a school camp - i need it gone by then) I’ve read about 25 different sites about many home remedies. I’ve tried salt, icing it, and I have some Zovirax I can use. Also I’ll be trying the tea bag method. I don’t want to try anything extreme, in case it just gets worse. Does anyone have any quick remedy? Thank-you in advance! When I say remedy, I don’t mean a cure. I just mean a way to help the cold sore heal and go away quickly, hopefully before monday morning :frowning:
