Have my 1st drug test ever on July 7th. Been clean two days now. I've been drinking water and exercising. I plan on taking some kind of B or multi-vitamin 2-4 hrs before my test because I believe diluting is my only chance. Testing for a hospital so I'm getting a physical which lessens my chance of synthetic piss. Also going to buy some home drug kits to make sure I'm clean. Am I going about this the right way??? Anyone have some advice for me???
