I am not a habitual smoker any more. This last weekend I smoked 3 doobs with a few friends from out of town, Saturday night to be exact. Last night i took 1 jet alert (200mg caffine) to make me pee and 2 niacin (250mg flush) then drank 96 oz (3qts) water. Urine was alomost clear. Today i am doing it again but adding coffee and metamucil (fiber supplement) to the mix. my test will be a cheap test and will be anywhere from 10am-12pm tomorrow. will i pass? i have fail test even when i havent smoked in 2 months. any sugggestions?
