beer and alka-seltzer

My uncle told me that when he was in the army he used to drink beer and alka-seltzer before any drug tests to clear his system and pass the test. He said that it would make him sweat really bad and piss like every five minutes then after that his test urine would be clean for a while. Has any heard of this, any truth to it?

i do this every month for my p.o.. it has worked every time for the last 2 years.. i use all drugs and it works .. trust me ..

how long before the drug test do you start drinking this combination? how much beer and how much alka-seltzer...a worried pothead would like to know
