Insomnia
"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!"
