I wouldn't until you know for sure that you have an issue. A lot of folks think this because they taste their sweet beer and panic. You'd be surprised how much sugar you really have in the beer. Besides, since you have no way to calculate how much is in there, re-priming will more than likely lead to a bottle bomb issue.
Wait 4 weeks to make sure you have a problem BEFORE you consider adding any more fermentables in there.
Trying to "fix" something that may not be an issue COULD become a different, and worse issue entirely.
