I feel soo silly for asking but it is driving me nuts... On Thursday evening around 11:50 to 12am I was given a 2 year old vicodin es to help with a bad foot. On Monday around 2pm I had a pee test. I totally forgot I took that pill! I am 5' 3" 137lb and walk alot thanks to my job. Could it have been out of my system? It was old and it had been 72hrs or more.
