I had 2 level artificial disc replacement to fix 2 ruptured disc in my lumbar area. I am tired of being on meds. I am tyring to ween myself off of the drug without using another narcotic to help with withdrawl. I am willing to just stop taking the drug. I need to pass a urine drug screen in 2 weeks. is this possible? are there any detoxifiers to purchase that would make me clean?
