I am 72 years old, have suffered from insomnia for years. My doctor has prescribed several sleep aids, but some don't work at all, and some have very adverse affects. Some sleep aids I've tried have an opposite, hyped up result. Could it be the insurance companies and not the doctors who disapprove. I have, in the past, been given clonazepam, and it worked very well... no bad side effects, no drowsiness the next day, no sluggish feelings. I get about 15-20 hours of sleep a week, and I can't function well on that little amount.
