I am really surprised to hear this. You looked so hard to find a neuro that would prescribe it and then didn't even take it correctly or for the 6-12 months to see desired results???

Not that there is any guarantee that LDN would work for you....but just that you didn't try.

The research is to take the LDN at night between 9pm and 3am. Maybe someday someone will do a research on LDN and preworkout....but for now there is no research in that area.
