Just as a data point, I had an IPA that I accidentally added about half again more corn sugar than I would have liked (I measured the corn sugar correctly, but had severely underestimated how much beer I would lose to the whole leaf dry hops, d'oh...) After a little over a week, the carbonation was starting to get a bit much for my liking, so I transferred it to the fridge. That beer's been my biggest success so far -- in fact, my wife and I have had to resolve not to drink any more so that we'll have any left for a party we're having on July 3rd!
But that was an exceptional case. If you didn't over-prime, then yeah, just wait please.
