Help! How much dillution is too much?

Hey guys,
So I have to take a pre-employment test today and I'm getting nervous. I took a home test 2 days ago and tested negative and haven't smoked for 8 days. I usually smoke about every other night with about 3 small bong hits a couple times. I want to dillute a little to be sure but need to know how much I can drink without them making me retest. I'm a avg/on the petite side female. I already drank a 20 oz Snapple this morning and am gonna take my test in about 4 hours. Any advice about how much more I can drink without screwing myself? I have heard the home tests are pretty accurate so hopefully I'm worrying over nothing. Any help is appreciated....

:hippy:

I'm more of a substitution person but I would think a small bottle of gatorade wouldn't hurt. If you passed your first void of the day you're already in good shape. Good luck...:thumbsup:
