"i took 2mg for 7 weeks.  at first, the after taste was the only adverse side effect although in retrospect within a couple of weeks i started having a dry cough. by the end of the 1st month i thought i had either a cold or an allergic reaction to something.  went to my doctor and the possible side effects of the was not even brought up.  i am coughing a lot and bringing up clear mucus.  i often felt like my throat is closing up and it reminded me of strep with how sore my throat was.  last night, completely frustrated i googled sore throat, cough and lunesta and found many other people had similar symptoms.  at first lunesta worked fine but gradually i slept less and the side effects were (are) horrible.  i&#039;m wide awake tonight!"
