I was diagnosed with Fibromyalgia three years ago. I am trying low dose Naltrexone. You start on a low dose of .5mg and work your way up to 3-4mg. I tried it twice before but discontinued it after a few weeks each time because I thought it was making my insomnia worse.

I am giving it a third try and this time it's working better. It might be because I'm not in a flare right now. Right now I'm at 1.5mg a day. I am sleeping better too but don't know if it's because of the LDN or not.

It's certainly worth a try. As far as I know it doesn't have to be tapered if you want to stop taking it. The only downside is that it's not covered by insurance and you have to get it from a compounding pharmacy since it's not available in low doses at a regular pharmacy. My pharmacy charged me $60 for 75 pills at the .5mg dose.
