How long after taking methadone does it show up in your urine?

Methadone might only take 3-5 days to get out of your system for a urine test but depending on the dose you are taking you will start to feel the effects of withdrawl starting on day 2-3. Than it might be 30 - 90 days before the effects of withdrawl are completely gone. It is the worst drug to detox off of if you try to do it cold turkey. It's 10x worse than coming off of Heroin and takes 10x as long. I've been on Methadone for 6 1/2 years and was forced into a detox when entering a county jail. I was medicated and my dose dropped from 160 to 0 in about 10 days and nothing after that. I did not sleep for 9 days until I was released and could get back to the clinic and let me tell you, you cant stand being in your own skin. You just want to peel your skin back and scratch your bones. I have heard of people not sleeping for up to 30-45 days. Seek a medical detox. If you have been on it a while, even 6 months to a year, detox yourself slowly and under a Dr.'s supervision. The pain, agony, frustration and all around anguish can be controlled by a DR. who knows what they are doing.
