CFS/ME patients response to low dose naltrexone

Naltrexone is an old drug which has been used mostly in heroin
addiction and alcoholism. However many doctors are using it it in small
doses to help in the treatment of numerous conditions including ME/CFS,
MS, cancers and auto-immune diseases. So far few standard trial reports
have been published but for those like me who have seen its worth over
many years it has made my work far more successful and satisfying.One CFS
patient came to me in a wheelchair the first time and on a motorcysle the
next time. There is a website with numerous patient reports at and further information at
