Eszopiclone
"I have really really bad insomnia. I'm up for 3 -4 days straight and after my doc prescribed me a combination of zopiclone and amitriptyline I'm able to sleep 4-5 hours but your body can become tolerant after awhile meaning you may have to increase your dosage. I've had to do this but what I've started to do is try to keep really busy throughout the day and if needed at night I'll take a smaller dose than prescribed to me or try to go a few days without it then take my regular dose."
