It has been said that a one-time high on a otherwise THC free body will take 3-5 days to test clean. (but how much will you smoke on Sunday night? - and how much fat do you have?)

Buy some home tests (online at under $2 a piece) or buy the expensive ones at the drug stores. Drinking liquids prior to your test and peeing a lot does not help rid your body of the THC. You can exercise all week but stop a couple of days prior to starting back to work. Take your hometest on the weekend. If you can pass your first void of the day, you probably wouldn't have to dilute much to pass your Monday random.

It's totally possible that you could smoke Sunday and pass (a week from) Monday.. but since everyone is different, the hometest would let you know.
