"had insomnia for years, due to anxiety and mild panic attacks, also complicated by dystonic tremor in my neck, head constantly twitches, even when lying down.  on a good night was getting 5 or 6 hours broken sleep.  tried several meds, nothing helped.  doctor suggested quetiapine, i was a bit reluctant as its such a strong drug but desperate enough to give a try. i&#039;m finally sleeping through every night!  very constipated when i first started but came right after a few weeks.  also wake up feeling groggy but am fine once i&#039;m up.   no problems with weight gain.  using 25mg but thinking about cutting down to 12.5mg.  love being able to sleep!"
