Melatonin is safe to take with anything. I was using 3 or 5mg melatonin and would pop three at a time, but I slept no longer or better taking that amount so I stopped, plus it made me depressed the next day.

Try, should be safe, or magnesium glycinate, good for sleep and neuropathy too.
I'm using cbd/thc 1:1 and seeking health magnesium capsules, minus vit B6, just to be safe🙂 only now and then B complex
Good to replenish magnesium, especially if you are using med.cannabis
