insomnia
"Some nights after taking the zolpidem I go right to sleep, and have sound, restful sleep for about 2-4hrs. Twice during my current bout of insomnia I have slept a full 10hrs after taking the zolpidem. I have had some positive experience, and some negative. However, I have bouts of insomnia once or twice a year; the past Zolpidem is worked really well, within few nights. I am not on week four of the insomnia, and three on the Zolpidem. I am working closely with my doctor."
