Insomnia
"I use Ambien CR 12.5mg (strongest), and I still wake up at 3am.  Can&#039;t take another Ambien. To avoid any risk associated with driving to work and then dealing with the drowsiness while at work, my doctor put me on Sonata.  Even if I wake up at 3 or 4, I am able to enjoy the rest of my night in restful sleep with no morning drowsiness at all.  "
