first of all, I take oxycotin 160 mg 3x a day due to a fall down the stairs that caused a spinal cord injury, and MRSA in my spine, so I have much pain for witch I take this medication that is prescribed to me by a Dr. But my problem is that before my last drug level screen I had been sick for 5-6 days, keeping nothing down and had diarrhea. Also I was trying to drink the green detox tea to try to help get rid of the bug that I had. Well my level of the medication was not showing up on the urine test. Is it because I had been sick and keeping nothing down or because I used the detox green tea?
