I was in the same position as a previous reviewer, Bern, and it was due to her review I decided to try this. Menopause, insomnia, tried allsorts including herbal sleep aids; however most of those were in tablet forms. Thought perhaps I was having trouble breaking down tablets (as I also have trouble absorbing minerals). As a previous reviewer mentioned, this product is very sweet & sticky. Palatable, but wowzer!? Anyway, I really noticed no effect, i.e. no drowsiness, either at night or next morning; but objectively, I have definitely had more sleep in the last week than for months before that. Still waking occasionally, not perfect sleep, but I haven\'t been up for hours in the middle of the night, so a distinct improvement. It can\'t be placebo effect, as I have tried many different herbal remedies without much success. Will carry on.
