So I got some percs yesterday and took 15 milligrams. This was my first time using opiates. I was still sedated from surgery(wisdom teeth) so I just fell asleep.

When I woke up a couple hours later, I was real lightheaded. It was giving me pretty bad nausea. Is there anything I can do to avoid this? Did I take to much?

Not really much you can do about the nausea. The morning after I had mine extracted I puked, but that was just because I had nothing in my stomach for 24hrs (didn't feel like eating) and had been taking a few percocet, for pain.

15mg is a fine beginner dose.

If I were you, I'd just save the rest of your 5mg's and just use advil to deal w/ the soreness. It ain't that bad, just irritating.

Nausea isn't uncommon w/ opiates. Nothing you can really do about it though, maybe have a light snack/meal in your stomach before you take some. Not moving tends to help also. Just chill out and let the euphoria engulf you :)

Take some Dramamine or smoke some weed, both will potentiate it. After a while you won't get as nauseus from opiates.
