My family member is looking for at the rapid detox program.  Some clinics offer Naltrexone implants, some offer shots, and some offer pill versions after the rapid detox.  I do NOT see anything after the process of this or any other follow up medication.  Are you claiming there is no requirement for after care other that counciling?
This whole process scares me to death for my family member but they have been struggling for years to kick this habit - detoxed themselves 5 to 6 times but relapsed - and I know they want to be rid of this for themselves, their kids, and their family.
