say u do oxy right. it takes 3 4 days to be gone from ur system. is it out in 4 days, or do u have to piss alot to get it out?
It should be out in 4 days by just sitting on your ass watching tv, but if you need it out quicker you might want to try exercising and drinking lots of water.
4 days most defintly = clean piss with oxy. now something like methodone or weed for instance takes 25-30 days to leave your system.
for those 4 days just drink likea nice big size bottle of water every day. or if your really paranoid you can get drinks that flush out your system. but u should be fine
If it's a blood test then it'll be a bit longer but yeah 4 days for it to be pissed if you smoke/snort it for sure if you drink lots of water and piss it all out... Maybe beer would be better? edit : LIGHT beer?
