I think you'll be fine. I actually had a test done at quest not too long ago. I was too afraid of using nay kind of flush, so i ended up going to a local head shop and got some quick fix synthetic pee and passes with flying colors. If you do the flush drink, make sure you follow the intructions right. If you decide to go with fake pee, make sure it's warm but not too warm. I tied a pocket warmer that came with it to my sample to get it warm, but had to take it off before the test because it was over a hunderd degrees. i passed for the job, but ended up taking an offer at another one where they pay me more and I don't get tested ever. I also get to work at home and smoke whenever I want. Now if I can find a hookup, I'll be the happiest man alive.
