This post may be a little late but if you haven't taken any in four days, I would imagine that they would be completely out or quite nearly out of your system already. From reading different threads on these and other forums, Hydro's leave the body fairly quickly (on average 3-5 days but that also depends on the amount you were taking which doesn't seem like too many due to you not mentioning any withdrawls) As mentioned by another, if you are afraid of any issues, take the prescription with you just to let the people know that you are on narcotics BUT, it is with doctors approval and not the type that you smoke [8D]
