To Dilute or not?

I've been surfing this section of the boards for awhile now. I have a physical for a job on Friday and I think there might be a drug test involved. (They never actually told me that but a friend who works for them now had to get one before getting hired)

Here's my scenario: I haven't smoked weed for exactly three months. Before that, I was a very heavy user. We're talking most of the day, everyday. It had been years since I had even gone a week, let alone a few days, without smoking. And we're talking pretty potent stuff. I'm a pretty skinny person and I've been exercising about 2-3 times a week since I've quit.

My question is: Do you guys think I should try and dilute the day of the suspected test or do you think I am clean? I know there are no definitive answers here but I have read in some places that it takes up to 100 days to get clean for some people. Is it even worth risking a dilute sample or having to deal with the uncomfortableness of having to go to the bathroom constantly? (I've got a very small bladder) Just wanting some opinions here.

Oh, and I did take a few home tests a month after I had stopped. There was a line-but so faint I could barely see it. I haven't taken once since.

Get yourself another test strip and see where you stand. With 90 days under your belt you should be clean. If your getting a line I wouldn't worry about diluting, just drink a 32oz gatorade before you take the test.
