Help with detox? Sorry, I'm sure you guys get this all the time :(

Hey guys can you help me out please? I need to pass a piss test for a job in two days. I didn't know I had to have it done by Friday until today and I'm freaking out. Here is the pertinent information:

Last smoke: Today, before I was told I needed to take the test by Friday. I took two relatively small hits out of a bowl.

Height: 6'0 Weight: 170 BF: around 10% (donno if this matters but maybe it speaks toward the pace of metabolism) Hydration: I keep well hydrated regularly. I drink at least 1 gallon of water a day Exercise: Mostly lifting. I do cardio maybe once every 2 weeks

Help would be GREATLY appreciated. Right now I have 3 gallons of cranberry juice, niacin (which I've been taking daily for about 3 days already), and as much water as I need.
