"i have been taking lunesta since about 2004. i have tried to take rozerem, ambien, ambien cr and nothing works as well as this. but now my copay is $76.00 a month on top of my doctors visit. the after taste does go away. i know it said not to take for a long period of time but i was not able to sleep with anything else but lunesta. now my insurance is changing again and i will basically have to pay full price. i love this medicine it is the only thing that works and i need something that could possibly be a substitute."
