I just passed a test, so Id like to help you out. I got the supplement Omni. It's often sold in GNCs and vitamin stores. Also, headshops will sell them. If you get it at a vitamin store, DONT say you need to to pass a drug test, they may not sell it to you. Unfortunatly, you only have til, today? Hopefully you didnt smoke in the last 20 some odd hours. DRINK WATER. I fasted and drank water for 24 hours before I peed and didnt smoke for 36 hours, so I dont know how well this will work. an hour and a half before you pee, drink 32oz of water, 2 bottles. Drink the Omni, the WHOLE THING. It made me puke twice while I was drinking it, probably because my stomach was full of water, but drink the vomit, too. Drink it down! haha.
Anyways, follow that with 16oz more water. Pee 4 times, and that shouldnt be to hard with all the liquid. I peed 1 1/2 hours after I drank the Omni. When you drink that much water, mixed with an extrodinary amount of vitamins and creatine, all you pee out is what you've just filled up on. I think the creatine is something they look for in nature urine. but you have to get the supplement, ifyou pee just water you'll have to test again...good luck, hope i got you in time!
