Replying to drug tests

so my parents are giving me a drug test and does anyone know how well adding visine works? I read everythign on erowid already and dnot hve much time so i was wondering if it is a better idea to drink a ton of water all day before the test and piss like mad and then add in some visine or should I get someone elses piss? It is going to happen with in the next couple days. My friends got home drug tests before and they just added in warm water and passed fine so that is what I was thinking of doing. Detox stuff wont help me to much casue I have no idea when the test will be so its likely i cant be drinking water like mad 45 minutes in advance. I know my mom bought an At Home brand drug test as liek a threat saying if she ever thought I was smoking again she would give me that so I think it will just be that but they might have me go to the doctor so I really have no idea what to expect.
