"certainly helps me to sleep. but first time i slept for about 12 hours which meant that i slept badly the following night. i now take 3/4 of the tablet for a solid 8 hours. i suggest trying 1/2 or 3/4 your first time the first half hour or so on waking leaves me groggy, then i&#039;m fine. also seems to help me sleep really well the following night. i use only occasionally."
