Have you heard of anyone else trying NMN and it not going well? It made me feel really loopy and also very tired so I tried it at different times of the day. I tried it in the morning and it just made me so sleepy, then at noon again no good very sleepy and before dinner, made me fell high and lastly at night and it disturb my sleep or I slept really awful when taking it. Maybe it's age related I am a 55 year old female, so I have stopped taking it.
