hello I have been surprised with having to take a standard urine test in about 40hrs. I have used about 120 milligrams of percocet "oxycodone" in the last 24hrs.before this I haven't used regularly for about a week.i don't want to get into the details only because it's very personel. I need any advice anyone can give me to help me to pass this. I've heard the water rumors but I don't know what I can believe.any advice anyone can give will be deeply appreciated.thank you so much.
