I've got an upcoming piss test and I just smoked this morning... the test will prolly be on Thursday. I've been taking niacin and drinking water... not lots of water but more then usual. I drank 1 packet of certo waited 1 hour drank another.... so 2.5hours after I took the first certo I took a piss test and came up positive.... that method didn't seem to have worked and I even used 2 packets.... any ideas?
