Some help, please.

I recently bought a chocolate bar from a reliable friend. I can't eat it for another 2 weeks or so (I have exams until then), and was wondering what would be the best way to keep it fresh. Should I refrigerate it? Freeze it? Also, will it lose potency by sitting around for a few weeks?

Thanks,
PB

 

i say keep it cold but dont freeze it. i dont think it'll lose much potency
