My daughter does and says it helps, I’m not sure if it’s just placebo effect though

A tiny pinch of powdered catnip will knock you out so quickly, it's better to get ready for bed before taking it.

There are some people who don't seem to produce enough .

It did not work for me more than once or twice. I know for some folks it seems to work maybe they'll chime in.

Melatonin didn't work for me, no matter how many minutes or hours before bedtime I'd take it. What does work for me, when needed, is a store brand sleep aid with diphenhydramine HCI. I still have to take it about 2 hours before I plan to go to bed for it to help, but it seems to work better than the melatonin I tried without success.
