"I have been suffering with insomnia for quite some time and have taken Ambien then finally Lunesta. The medication just didn&#039;t agree with me. I would often wake up in the middle of the night with a bad taste in my mouth and a nasty headache. When I did sleep, I would be washed out the morning after and very angry, irritable. I was becoming a different person and felt very sad. My fuse was short. Ask my family. I asked my doctor about Silenor and he gave me 3mg sample to try. I have never slept better in a long time. I woke up feeling fresh without the drowsy symptoms I had to put up with while taking Lunesta. No more attitude problem. Family loves me again. Also, I was a nut while on Ambien so forget that. I will stick with Silenor now."
