insomnia
"I took Lunesta only for a few days because it gave me unpleasant taste. It was really bad. Then I switched to Ambien. It was better than Lunesta, but there was a residual effect that the medicine made me irritable and anxious next morning. My doctor gave me Silenor. It is better than Ambien CR. I do not feel anxious or irritable next morning and I can sleep 8 hours. The only side effect, though very minor, is that it makes me sluggish a little. But, overall, Silenor is better than Ambien CR. "
