the only sure fire way to pass a drug test is time. suregel works but it can cause sever stomach pains as it turns to a gel in your kidneys. i've seen it work first hand.
directions- add 1 box of suregel to 2 liters of gatoraid, drink within 1 hour. then drink the same amount of water. pee atleast 2 or 3 times before the test. you should show clean for a few hours after that..
now again i'll say. this stuff turns to a gel in your kidneys and stays that way for several hours so it can cause sever pains. if you don't pee a few times before hand then it won't work.
the best advise i can give is stop smokin if you gotta take pee tests more than once every few months. jmo
you can find suregel in most grocery stores on the same isle as jello.
