Heck, I even took 120mg of Codeine the other day, but I'm nodding out like crazy right now on a single 10mg Hydro. I'm delaying my 5mg of Valium till later (take 10mg a day) even though I usually take it now, just to be safe. I'm itching like crazy all over my face lol, love that feeling. Is it because Codeine has to be metabolized? I wouldn't even want to take more hydrocodone with how high I am right now, not to mention I want to be safe.
