insomnia
"This is by far the worst pill prescribed for sleep! !! I felt anxious  irritable. ..heart was racing headache  and my blood pressure increased  along with abdominal discomfort and muscle pain. And if I I do fall asleep  it's for an hour or so  and I'm up for another hour and find it very  hard  to fall back to sleep . Never again !! this pill is not  for me!!!"
