i suggest you find a new job offer, honestly. "over a 28 day period" tells me that you just don't remember, and that you were most likely using about a half gram a day, on average. you've been essentially using more than moderatly. you've been using regularly. don't expect to pass this. drink shitloads of water, and take vitamins. take anything that colorizes your pee. don't let your piss test be the first test of the day. i'd personally wake up at 4 or so, drink a shitload, piss your first of the day, piss again, and keep drinking all the way through this. i'd drink gatorade, not water, just for some potential colorization, if that's in any way medicinally proven.
