Zolpidem
"I take Zolpidem two or three times a week if I have had a very busy day and am not relaxed enough to sleep. It works well and will put me to sleep within 30-45 mins. Zolpidem works much better for me than benzodiazepines do (due to its longer half-life). If you are going to take Zolpidem do not take it every night. It can be taken 2 or 3 times a week without losing your natural ability to sleep."
