Insomnia
"I was taking Ambien 15mg for awhile but my body built a tolerance to it.  Over 2 weeks ago my doctor changed my prescription to Lunesta 3mg.  I finally got up the nerve to take it after doing all the research.   This is the first I have taken and I must say the aftertaste after about 5 minutes of taking it is absolutely HORRIBLE.  Even breathing in through my mouth or nose heightens it.  It strongly reminds me of how my mouth would taste after taking chemotherapy for cancer.   It&#039;s causing a horrible flashback for me.  This will be the first and last Lunesta I take.  You also can&#039;t eat or drink anything as it tastes horrible too.  I guess I will have to go back to Ambien."
