well most of us are uk-based pharmacists on these forums (a big hello to all of those that aren't!) so would really only have access to the same sources of information as yourself regarding nardil.
Uk based pharmacies cannot currently supply prescriptions to patients from the USA as far as i am aware - because they are subject to the uk medecines act which prohibits supply of prescription only meds to prescriptions from non-uk registered doctors.
Many other countries operate similar systems (with regard to international prescriptions) to the uk eg australia and possibly NZ too.
However some less regulated sites in other countries will supply almost anything without prescription - the drawbacks of this are:
(a) If it's a POM theres a bloody good reason why you shouldn't be able to just buy it.
(b) The majority of these 'grey' sites supply fake / dangerous or out of date products which do more harm than good.

I'm quite surprised that you have to be so brand-specific with the nardil though. Wouldn't a US version of the drug be roughly bioequivalent to a new zealand produced version? The active ingredient would have to be the same - although additives to the tablet may differ slightly they shouldn't affect the action of the drug in your body.

Have you spoken to your local US-based pharmacy? they may have access to the specific brand via overseas/special ordering systems for you.
