"this product works, not as well as zolpedem but it works. i know that drugs work different on each person and can only tell you what it does to me. i first took it at 11 pm. got very drowsy and slept mostly through the night. if i was woken up by my wife getting up or the cat jumping on the bed i went back to sleep. the problem is i woke up very groggy and it lasted till 4pm the next day.  the next night i took one pill at 8:30 pm and i was groggy till 3pm the next day. zolpedem made me sleep through the night and i woke up fresh and awake. i don&#039;t know if i can take this product very often."
