No there's not. Smokey, get some soluble fiber like metamucil and see if it helps. If you get the caps take 6 caps 3-4 times a day.
FakeBoobsRule Reviewed by FakeBoobsRule on . Passed home test 3 days and 4th day failed? I passed my home drug tests for three days after not smoking for 23 days -- the forth day, after taking a prescribed Xanax the night before, I then failed twice today. Does this make sense? I thought once negative, always negative. Does Xanax cause a false positive or is it common for my test to turn around and go back to negative? I haven't changed anything else so I have to attribute the failure to the Xanax. Am I making the wrong assumption?:(:(:( Rating: 5
