I'm on Percocet, and I had to have a prescription - no refills, I have togo back for a follow-up every month or I don't get my new prescription. Sorry, it isn't as easy as that. But at least here in NB, it isn't expensive either - I think it's about $50 for 300, or about $30 US.
But you can still come for a visit ;)
Hugs,
Nancy
