Stimulants, drink water to the point of hyponatremia (http://www.erowid.org/culture/health...oisoning.shtml) or maybe not quite that much. cranberry juice suposedly helps, worth a shot. drink drink drink is all you can really do, there are all sorts of suposed ways to flush your system, i was on probie so i know what its like to worry about testing. try to delay it if you can, its worth faking sick to put off a test IMO. good luck, check the testing vaults on erowid.
