"i wanted a pill to take when traveling to sleep.  to test it i took 50 mg at home , when i would normally go to sleep without anything.  after a few minutes in bed, i had difficulty swallowing, it was scary.  i drank some water and it went away.  i did not sleep at all, after 2 hours i took an ambien.  i had taken this pill one hour before bed.  a week later i took 25mg as prescribed, cut the 50mg pill in half as directed.  took it 1.5 hours before bed, no swallowing problems, but after 2 hours, still awake. took ambien."
