"i don&#039;t have crippling insomnia, but i cycle through rough periods of it. zopiclone 7.5mg has worked well for me. i fall asleep within half an hour of taking it if i am in bed, lights off. it gives me a good 7 hours of rest most of the time, but i track my sleep quality and sometimes the quality actually isn&#039;t that great. i need to be in bed when i take it because if i stay up for more than ~30 mins after taking it, i can&#039;t fall asleep. super frustrating, but avoidable."
