The dosage depends on your drug of choice, how long
taking it, how
much daily, and many other factors.
I have rx insurance, but I know how
expensive it would be without! If you can't afford it, there are other options for getting off fentanyl. Methadone is much less expensive, but has it's own issues. Try finding someone in your area that won't charge for a consultation regarding Sub, and pick their brain about it! There is lots of info available online at subutex.com or suboxone.com.
