I honestly have found only one thing over the counter for sleep that. Occasionally works is Aleve PM. I was taken off Belsomera for insomnia because it makes my narcolepsy worse but so does no sleep..

Personally, Over the counter sleep aides haven't helped myself.

It didn't help me but I do know without sleep...it makes it worse.

Don't know what I have heard that taking melatonin over a period of time could affect your ability to sleep
