Hi,I am prescribed 4- 7.25 percocets a day. I just had them filled last Thurs. and on Sat. night they were stolen. I did take all 4 of them on Sat. Then .on Mon. morning I went to my dr. and he gave me another script but I had to take a urine test and I wasn't worried at all about it. The following week I received a letter from my dr. saying he was dismissing me because I had percocet in my system. I need 2 knee replacements so I'm not active at all. Also I don't drink enough, my kidneys shut down last year because of it. I only urinate about twice a day. So isn't it possible that I would still have percocet in my system?
