I really like how fast it works for me and my son, we're both down for the count within half an hour or forty minutes. I sleep about 6-9 hours a night, depending on whether or not I wake up and can't go back to sleep. I knew about the light receptors and their sensitivity to light if you're in the half sleeping stage, light can definitely wake you up fully. Thanks everyone for the great replies!
