I can't find the post I was looking for where someone told me about low dose naltrexone for fatigue, focus and energy level. I asked my neuro about it and even sent him some of the message I thought was very relevant. Long story short, here is his response:
"There has been some research done on Low Dose Naltrexone, however, this has shown that this medication is not effective for multiple sclerosis. It certainly doesn't help with fatigue symptoms. I wouldn't recommend this medication."
So that's the name of that tune...I'm open to other suggestions, not optimistic.
