I'm a retired RN and I worked night shift for most of my 30 years of nursing. A few years ago I asked my Dr if there was anything that I could take to help me sleep at night. I was unable to turn off my brain, regargless of how tired my body was. He prescribed Ambien and I have taken it ever since. I tell my doctor every time that I see him for a refill that this pill literally changed my life. My husband completely agrees. I plan on taking Ambien till the day I die and thank God for it every morning.
