Sort of related, but I bottled a Cooper's IPA with a little over 2ozs of dextrose and it carbed nicely for what I wanted in about 2 weeks. Kept them on the cool side too. I was going for a lightly carbed "casked" feel I thought, although I've never had one. I'd say just wait another week, then stick one in the fridge for a couple days before you try anything drastic.
Don't even break it out if you ain't gonna share.
