insomnia
"I love Sonata, for the first time I can sleep. However, I think it works best if you wind yourself down and relax a bit first. Otherwise, I would find myself feeling the effects of the medication and still active and now impaired. So I learned early in once I stop what I am doing and just relax, watch T.V, read a book etc. Right to sleep and I stayed there. Not groggy at all the next day."
