OTC wild yam cream for insomnia post menopause

Since menopause I wake up in the middle of the night and cannot fall back to sleep. I tried everything, except Rx drugs. The one thing that worked was CBD tincture, but I prefer not storing that in my liver month after month.

A friend told me she used wild yam cream, and it helps sleep issues tremendously. I guess yams produce a sort of progesterone that helps us sleep. I just started using it this week, so the jury is still out. Anyone out there have feedback on this topic? Thank you.
