Yes. If prescription drugs or any over-the-counter medication (including NyQuil) affects your driving, you can be charged with Driving Under the Influence of Drugs (DUID) just as easily as someone who has taken cocaine. Unfortunately, many people try to defend themselves by saying, “It’s ok, I have a prescription,” which is then used as proof of their guilt. This is one reason you should never give any information outside of that related to your identity if you have been pulled over by the police.
