Help How to overrun a urine drug experiment when you own taken agony killer?

I have be taking endocet and hydroco for my back pains but they are my dads pills. I enjoy an interview for a job I cant leave behind up tomorrow and i know they do urine. I dont know what they look for but i remember long time ago taking a hair check for a casino and i have taken something next to codine and i failed because i didnt own a perscription to show for it. I took one this morning at 3 am and one at 445 am and i have taken them for a couple days contained by a row. My interview is tomorrow at 1030 am and i am sure they will want to do a drug test inside 24 hours. ANyone have any guidance i could sure use it. My life pretty much depends on this employment but i hurt my back at work a year ago and i enjoy no insurance to get my own pills. Thank you. It won't show up in a urine exam, I don't think so anyhow because I own taken tests up to that time and never heard anything give or take a few it and I take misery killers more than I have need of them.
Thats the terrible side effect of Narcotic's, i to enjoy been on MS cotin and Oxycodon for a yr, I enjoy asked repeated times to my dr, would I pass a drug try-out, he and she and he and she say unquestionably NO, and u can become a liability to the company, if u get hurt they do a drug check and if they fiend out u are on these drugs they will fire u and can sue u for reason for liability causes. Sorry,
