LDN - questions

Everyday living
1

So, I decided to give it a try and my consultant agreed to write a private perscription for 3 mg of LDN for 3 months. I have 3 questions:

  1. Isn’t 3mg a bit much?

  2. Where/how do I buy it?

  3. How much will it cost?

Thank you very much in advance,

Irina
