I never had sleep problems until I was diagnosed with pancreatic cancer. At least nothing that I couldn't conquer on my own. Now sleep is the fatherest thing from my consciousness. My doctor gave me ambien and it is fantastic. I am not a druggy. Don't even take asa or vitamins except once in a while. So I didn't want to take a sleeping pill, but no choice. With ambiem I NEVER have a hangover, no matter how many hours of sleep I get or don't get and it takes effect in just a little while. TIP: it will have more of an effect on an empty stomach.
