I say, consult a pain specialist, if this guy you're seeing isn't one, rather than an addiction specialist, FIRST. If you take morphine
for the right reasons, what have
you got to be ashamed of? That not being an addict; you're just experiencing the inevitable side effects of this class of drug.
Whatever you do, don't let you're programming result in you denying yourself enough morphine to relieve your pain, yet keep taking too-small doses that will leave you in pain AND leave you dependant.
