The way the LDN works is it blocks the opioid receptors in the early morning hours which produces an up-regulation of the immune system...which in turn results in an increase in endorphins and enkephalins.
I tried it in 2013 before I knew I had lyme...I though it might help with my daily pain.
It didn't work for me. I ended up getting pain waking me up at night after I started taking it.
I may have increased the dose too fast....perhaps.
Here's the (rudimentary) website where I first read about
LDN:
