"lunesta is wonderful. i am a chronic insomniac that can&#039;t sleep at all without medication, so far (2 weeks) lunesta is the best i have ever used.  i have been on 9 different sleep medicines from antidepressants to benzodiazepines, etc. and 3 mg lunesta has helped the most. i was on ambien for some time, both regular and cr and with both i would wake up after 4 hours. lunesta gets me a solid 7 hrs of sleep and has changed my life! only bad thing is the taste but i am getting used to it now, oh and it isn&#039;t cheap! patent expires in 2 years then generic will be available, but this medicine is worth the cost, nothing else works as well for sleep onset and maintenance."
