methadone and a employment urine test

I am back in the same position I was in about a month ago.I have found a new and better job than the one I have now.I will have to take a drug test to get it though,but I am pretty sure it will be the same 5 panel urine test I took just a month ago.Last time I had just 24hrs notice,and had taken 180mg of oxycodone about 20hrs before test.I went out and bought a detoxifying drink"stripe" I belive it was called.I did end up passing the test.Now on this test I will have more prep time,I do need to take some oxy's just so I don't have to go though withdrawl's but I plan on taking as little as possible and going for as long as possible before my test.But the real question is about methadone,I had taken like 30mg a day for like 6 days in a row but that was like 2 weeks ago.Does any one know if it shows up on the 5 panel test,or how long it even stays in your system.And if I drink as much water as I can stand for like 2-3 days before test will that help not just with the oxy's but with the methadone as well.

 

before any one posts,I did read up on it on erowind,or whatever that site is called,but any new info or personal experiences would be appreciated.

 

Methadone has to tested for individually. No one I have ever heard of tests for it. I have been on it for 4 years and I pass every test at my hospital with flying colors. In fact use the methadone to keep withdrawls at bay during test time if W/D's are a problem.
