HI, does anyone know if there is something you can take for a drug test, that will cover up the parts per million. The parts per are like 3 or 4 a day, what if you take more that? A drug test will show the level of hydro wont it? I am perscribed this by my dr. but only 3 a day. It is a urine test i have to take so i'm not sure what to do about this. Yes i have the bottle to show but what about the level being higher than its suppose to be? If anyone could help me with this i would feel a lot better!! Thanks
