Success with low dose naltrexone for Autoimmune disorders

Low Dose Naltrexone, otherwise known as LDN, seems to be helping a lot of people lately who have all different types of autoimmune disorders.
The information I read sounds very interesting and would like to know if anyone has tried it personally?

The theory that I read says that many autoimmune issues are caused by a deficiency in endorphins, endorphins regulate the immune system. LDN temporarily blocks the body's natural endorphin production for a few hours, this tricks the body into thinking it needs to increase endorphin production. When the blockade wears off, all the endorphins are released into the body, regulating the immune system and providing natural pain relief for the rest of the day. Apparently, LDN can increase your endorphins by up to 300%

LDNscience.org has a lot of information and research about it. You can also look at the writer, Annie Habler (@hablerannie) on Medium.com who wrote an article recently about the fascinating background and history of LDN.

Please let me know if you have tried it and what your experience was like. If you could let me know any details your condition,the dosage you used, any side effects, etc it would be helpful.

Thank you!
