From what I know about available sleeping pills on the market. I believe 5 to 10mg. of Ambien is a better choice than Lunesta 5mg. But that is only my opinion. I believe Zolipidem or Ambien achieves a better effect than Lunesta and is more efficacious. Always ask your doctor about any medications that you plan on taking, in case there are any concerns. Also ask him or her to prescribe Ambien it its generic form, which is Zolpidem. It works just as well and better yet is much easier on your wallet. Both Lunesta and Ambien are controlled substances and only available with a written Rx from your healthcare practitioner. Also I have a relative who purchased a natural sleeping remedy called nerve eight. She takes two of these natural herbs before bedtime-and I am told she sleeps like a baby. Nerve eight is availabe online at the following website. www.naturessunshine.com Hope I have helped answer a few questions that you had in reference to sleeping pills.
