insomnia
"I have had severe insomnia for about 3 years. My physician gave me 2 sample packs of 6mg Silenor.  I cut them in half to take 3mg as needed. They worked wonderfully and I finally got several good nights of sleep without the groggy feeling in the morning. After the samples were gone, I got my Rx filled and found out my insurance will not cover it.  After having been awake for 36 hours straight, out of desperation, I paid an arm and a leg for the Silenor. The first tablet of the Rx worked but that's it.  I Increased to taking 6 mg and it still didn't work. Still no sleep. I have given up on Silenor and have gone back to a different insomnia Rx that works sometimes but at least my insurance covers it it only costs me $5."
