This is a really GREAT sleep aid for me. I used this light blocker for a few years (before the USDA ban .. contaminated product from Japan) and when it was pulled from the shelves I went to melatonin. This company (NOW Nutrition) makes a quality product that I am delighted to have found again.

I used the NOW L-Tryptophan for about two weeks. It definitely helps with a deep sleep, but I started to notice I was getting bad dreams. I know my dreams are associated with my own stress, but it seemed magnified while taking this supplement and I would wake up feeling emotionally exhausted. I've switched to Melatonin, which seems to work a lot better for me.

This product did not do anything for me. However, that does not mean that it would not work for others.
