Need Some Advice on Testing

Taking a new job on 6/1 and there's a possibility the company might test. I'm not about to ask, because that's just way too suspicious.

So here's my situation:

I'm 5'11, 220lbs. I ride Mountain bikes 1-2 times a week for about 3-4 hours each time. I don't work out in the gym regularly, but I'm fairly in shape for the activities I do. I could, however, lose about 35-40 lbs to get me in the right shape for my size and age. I do have a pretty good sized belly (man it's surprisingly easy to be honest when you're anonymous).

I started smoking about a year ago, and after about 6 or 7 months of usage I pretty much became a daily user. I smoke with a small water bong, and usually use about 1/2 bowl weeknights and a bowl each day on the weekends.

As soon as I had my interview, I stopped smoking. That was on Monday, 5/16. I got the offer the same afternoon, and I start the new job on 6/1.

The only other thing that might help paint my picture is I'm on the "gallon of water a day" program. A bunch of guys at my current job had a contest to see who could drink a gallon of water each day for a week. After the contest ended a few of us kept doing it, cause we were hooked. I don't always get through a full gallon, but I always get through *at least* half a gallon a day (and spend half my day in the john).

So... big guy smokes pot every day, drinks at least half a gallon of water a day and rides MTN bikes 4-8 hours a week. That's the picture.

I don't mind spending the money on an expensive cleansing kit, but it sounds like most of them are bogus. There are SO many websites, I don't know which ones are trustworthy and which ones are sending crushed asprin in a pouch.

This position is one of a lifetime, and it kind of fell in my lap so I wasn't prepared for this. This is also the first time in my entire life that I've had to deal with this (remember, I just started smoking last year). So I'm pretty dang nervous about this.

If I continue to pound water, and mix it with asprin and Vitamin B will that be enough, or should I get a cleansing kit? I read N2Pot's big post, but it seems most of what he suggested was for the day of the test. I don't even know if I'm going to be tested... so I'm not sure how much that helps.

With 14 days left to go before I start the job, what should I do? Get a kit, or continue to pound the water? Any help would be greatly appreciated!!!

Thanks!
