I seen my suboxone doctor the next day and had a random drug test. I refused it so the doctor cut back my dose 1/2 tablet and I have one chance to redeem my self in 2 weeks when I get drug screened. Anyway I took an 8mg sub the very next day after using heroin the day before. I did not experience any preciputated withdrawl! Is this because of my high metabulism? Or some other reason?
