I Am 76 Years Old And Have Had Prostate Cancer,

I am 76 years old and have had prostate cancer, 5 heart stints and had sleeping problems. My doctor recommended Tamazepam. I take one at night but for the past 6 months I have trouble getting to sleep after I take the pill. I am also on Casodex, Metoprolol simivastatin, effioent and Biclulainide I take many vitamins. My problem is getting to sleep after taking this pill. Steve @ YYYY@YYYY
