"i have lived with severe insomnia for 34 years due to a circadian rhythm disorder. when i say that i have tried all sleep medications, you can believe me.  my doctor gave my a voucher for a free trial of belsomra. i was skeptical, then saw a review someone had written who had a very similar sleep disorder. he said to reach more areas in the brain that control the sleep-awake switches,  to try it with 1 milligram of melatonin,  50 milligrams of diphenhydramine, and a 1/4 milligram of a benzo. i haven&#039;t slept like i did last night since i was a child. i gave it  7/10 because i don&#039;t know yet if it was a fluke, but i am hopeful that it will continue to work."
