insomnia
"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'm fine. Also seems to help me sleep really well the following night. I use only occasionally."
