"That's the most important thing I can say about this product. I take one or two capsules an hour or less before going to bed. I also use 1 mg. of sublingual melatonin which I put under my tongue just before retiring. After this I go to sleep quickly and usually sleep through the night. This product is also a good value, especially when on sale!"
