Im on other pain meds, like methadone, i also take colazapam for anxiety,& im also on bupropion for anti-depressant(200mg) methadone(50mg) colazapam(0.5) Do I really need this for my nerve pain in my back & leg??? Im sure my doctor wouldnt perscribe any meds that would harm me,but its sometimes good to get another apinion. Thank you JD
