@363 LDN is low dose naltrexone. Naltrexone was originally developed to treat opioid addiction at high doses, but studies showed that at low doses it helped relieve pain from fibromyalgia, Lymes disease, and other conditions including poor sleep. I started taking it in early 2025 for my fibromyalgia, but found that my insomnia also improved and now I sleep well every night. There's many articles on-line if you google "LDN to improve sleep".

Here are a couple websites:

You have to get it from a compounding pharmacy because it's not produced by drug companies at the lower doses. Also it's not covered by insurance. The maintenance dose is usually 4.5mg/day. You have to start at a low dose and build up to 4.5mg/day. Then it can take several weeks to notice improvement. Most people have no negative side effects (I haven't noticed any except vivid dreams).

My cost for LDN is $115 for 90 day supply. I got my prescription from a Dr at a pain clinic, but my PCP also prescribes it. I live in MN and my compounding pharmacy can help locate a provider in our state. Otherwise, maybe your local pharmacy can help locate a compounding pharmacy in your area.
