Insomnia
"I am bi/polar and awaken many times around 2 or 3 am with racing thoughts. This makes it impossible for me to go back to sleep and I am exhausted because of it. My Dr. had me try the Sonata and with taking it at these times I can get another 3 to 4 hours of sleep and  awaken feeling very rested. I usually fall back to sleep within 15 minutes after  taking it. Love it on those rough nights."
