Answer: Lunesta is VERY good.I have terrible insommnia due to Fibromyalgia, peri-menopause, etc.I have used Ativan, Valium, Benadryl, Ambien, Flexaril, none helped.Lunesta is great, best sleep I have gotten in over a year.It does make me have a metallic taste.Just be sure you take it and go to bed right away,it knocks you out pretty soon, and make sure you are planning on sleeping at least 6 hours or it could be dangerous to drive the next morning.Start out with lowest dose, thats what I did for 1st month,then I went up to 3mg.
