Lisa, LDN is short for Low Dose Naltrexone. We have a thread way up top, on the main page, that says LDN Infromation and check-in part 2. We discuss the drug and how we are doing on it. There are other drugs discussed up there also.
LDN had been helping many of us and it cost very little a month. It is a pill you take a bedtime. That's it. You need to get a Neuro or a PCP doctor to prescribe it for you, and then get it from a compounding pharmacy, like maybe Skip's by mail in Florida.
Here is the website to what LDN is all about. Many on here have taken it for 4 to 6 years. I am new to it, almost 8 months now. It has helped me greatly.
