insomnia
"YES, Lunesta 3mg provides me GREAT REST! It seems to not have the tolerance problems that Ambien has. I've used Lunesta for over a year (when required). It did give me metal mouth taste but after a while I began to look for that taste when drinking water during the night. I guess some will adjust to this side effect. Other side effects, a hearty appetite, hunger for sweets, loss some libido but still tolerable. The bad news is the maker was granted an extension to its exclusive rights till 2015 which means no generics till then and the highest co-pay every month! It's the high price of a quality nights sleep."
