Moose,
Congrats on getting the LDN.
Yes, I know of people who couldnt get the LDN prescribed by their docs and couldn't/weren't willing to pay mega buck$ for consultation by a holistic doc, and they got their LDN from alldaychemists in India, ordered it, made their own liquid LDN, and have had success.
With LDN (regardless of its form, i.e. liquid, oral pills, transdermal, etc...) there are only 2 contra-indications: no alcohol and no opioids of any kind.
Also, LDN is much more successful with a gluten, dairy, wheat free diet.
The reason for this is because the cell receptor site used for naltrexone or LDN is the same as the one that alcohol and opioids use, therefore they would each be competing for the same receptor site - and wouldn't work.
Good luck with the liquid LDN and do let us know how you make out with it.
