Too answer your questions already, i looked at the stickies I am 5'10 185lbs and pretty fit. I have smoked once a week for about 2 months, and once yesterday (Weds night), got a call saying i have to drop tomorrow at 1pm (Friday)..... I've been slamming water and running, and i bought some omni extra strength flush... guy at the counter said i needed 48hours, but said i should be good with around 40. Plan is to go by some cranberry juice and slam water and work out all rest of tonight, then slam the omni 2 hours before the DT tomorrow and drink water, then piss mid stream......... WILL I PASS!?!??!
Its really hard to say, if you flush your system enough you might be able too. The best thing you could ever do is postpone it. Please don't over work and kill yourself.
