Yes, I am amazed at your neuro's lack of knowledge regarding LDN!!! There are "zillions" of websites, forums, etc., where information is shared. It's such a shame that a side-effect free (for most people), inexpensive pill is dismissed by so many when it can produce great results. It certainly isn't a narcotic since higher doses are used to help people get off heroin. From my experience, the "narcotics" prescribed by our doctors have more ill effects than LDN ever did. Okay..........I'm off the soapbox now!

FYI......SPMS is Secondary Progressive MS. It started off as RRMS then progressed over a number of years with fewer flares but symptoms remain. In other words the downhill slide really begins.
