I have been on LDN - the pills - for about 3 months. I have found it to be a miracle worker. I am now walking distances without breathlessness and most days, I have more energy. I moved from taking the LDN with dinner because of weird dreams and sleep disturbances and now take it each morning with breakfast. LDN has not taken care of all my Long Covid/CFS and fibromyalgia symptoms but I do feel so much better. I titrated up to 4.5 mg. I had balance/dizziness problems and gastro issues before LDN and continue to have those symptoms.
