I have a piss test thursday, smoked sunday night also got shitfaced. My question is, will drinking alotta alcohol help make you clear for a urine test? Considering beer/liquor really flushes your system, I'm sure someone has clarified that but I'm a noob when it comes to piss tests. I have 2 40s, weigh 118lbs, should it work? I've been chuggin alotta water as well. Eh, edit, how well does vinigar work? I hear it just dilutes the urine, but how true is this?
