When I first started on this drug, I was amazed at how good I felt, and how my pain levels were reduced. But now, for some unknown reason I am not having the results I was enjoying before. My pain levels have gotten higher and I feel exactly the way I did before I ever started taking the LDN. It has been about five months since I started. So for an experiment, I stopped taking it for two days, and felt better than I had in a long time, even though I am still in pain. I am puzzled about this development, and wonder if this has happened to anyone else here?
