insomnia
"Lunesta is wonderful. I am a chronic insomniac that can'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'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."
