It worked for a week and a half, or helped with energy and less pain, and was able to get off Vicodin. Then when I tried to raise it to 4 mgs, dizziness, splitting headache, etc. hit, so I lowered it...had to go as low as 1 mg for side effects to go away. Tried to get back up to 3 where I had experienced something sortof good, but could never get up that high again. Just got splitting headache when I tried to raise it. Then more pain all day long...wanted my Vicodin back! So I threw in the towel. Quit it, and felt much better, and happy to be back on Vicodin, which seems to keep pain away all day, til I hit the sheets again and aching starts up again.
Very disappointed LDN didnt work for me. No source, but a friend told me it works best for those with auto immune illnesses, like MS, lupus and RA.
