I have been addicted to opiates due to 3 back surgeries. I was in severe pain for a solid 5 years?Taking 8 norcos a day... the10/325's. My dr put me on subutex and saved my life. My question is I'm taking 8mg subutex, half in the morning and half at night for 2 years now, if I just stop now will there be HUGE withdrawals or what from here? What is 8mg compared to vicodin? So I takke 4mg in the morning and 4mg at night of subutex?
