It's helped me for quite some time - I've pretty much tried it all: Valerian (and one year I had been so distraught that I took 6 caps. a day and it didn't do me any good in relaxing me), Passionflower (only at night), Melatonin (again only at night), L-Theanine (day and night was ok for me)...but I'm finding that Ashwagandha helps me the most because it helps me get very good sleep.
