insomnia
"I've taken Lunesta for a year and as a night shift nurse I'm able to take 3mg and sleep solidly for 5-6 hours while the sun is shining outside. When I wake I'm ready and refreshed for another 12 hour overnight shift. The funny taste goes away after a while and is worth the benefit of a good sleep. I recommend taking it on a relatively empty stomach then jump in the sack in a cool room and close your eyes try to calm your breathing then let the sleep come to you. A good pair of comfortable earplugs may help too."
