Hi Caya, if you want to find more information on LDN and how to go about obtaining a prescription etc, your best bet would be to join the yahoo ldn chat group below. There are some people there that can help but the site is somewhat scattered. The problem with LDN is that most docs will not prescribe and it can be expensive if you have to pay a doc for a consult for an Rx. In the meantime, maybe you could look at the "dextromethorphan" thread on this site.
Regards, Ashley
