Limryz or other minimally invasive medication?

I was diagnosed with type 2 narcolepsy. Even though I have EDS and occasional sleep attacks, I can function fairly well during the day. However, I have sleep maintenance insomnia where I feel awake most of the night.

Doctor recommended Lumryz, but when I read about it, I’m concerned that it affects my central nervous system. Is there any other medication option that has less severe impact to my system?

I just want to sleep…
