Took percocet for one after surgery and took my last dose last night. this morning i am feeling "foggy" and a little lightheaded. is this normal?

Take care with opiod: Oxycodone and acetaminophen (Percocet) is a very powerful medication and you should take great care when taking it. I would not drive or do anything physically where you may fall when you feel like this. Call your doctor and communicate with him/her about how you are affected by Percocet. If your pain is well controlled, you may be able to step down to a less powerful narcotic or non-narcotic med.
