Help Please!!!!! I have a Drug Test today!! Been using Meth up until yesterday for a week. What do I do?

I know people! I know!
I really need help on this one!!

Yesterday was my last day of using this drug or any drug period!
I am being tested randomly by probation and sick and tired of all the problems that associate with drug abuse.

I’ve been on it for a week and I know usually it takes 3 days to get out of your system.
I heard Baking Soda & Water helps but is that true?
Or is there anything else?

Please Help!!!!!!! Please!!!!!!!!
