To test LDN myself I took it for 3 months. It did nothing but make me drowsey at night, which I do not need because I sleep like a baby already. My guess is that people who experience a benefit are simply getting better sleep, which can be achieved in other ways.

Since there is NO evidence that LDN works to relieve symptoms, other than anecdotal, and even that is sparse, I have discontinued it.

I am taking 25/100 Carb/L-dopa 4 times a day and having a difficult time with dyskenisia daily.
