I started taking LDN about a month ago....starting with 1.5 MG then 3 MG and just last nite went to 4.5. I felt a little weird during the nite and sleepless... like maybe the dosage was too high....or do I stick with this dosage and give it time. I know overall one has to take LDN before you can tell if it's working. I do believe I have already had a little improvement.
