"i have long qt syndrome.   so i can not take anything to help me sleep because it could cause cardiac arrest.   however i have a horrible time trying to fall asleep and stay asleep.  it&#039;s terrible.  but i can take belsomra safely.   and it has been a god send for me.  i take the 20mg dose and as long as i am in bed at the time it kicks in , i fall asleep fairly easily and stay asleep for a solid 6 hours. i wake up feeling refreshed.   ( i had a bad case of insomnia- 3 hours to fall asleep.. waking up 4 or 5 times a night-  getting 3 hours of sleep a night if that)  belsomra has made sleep possible."
