There is a risk of dependence when taking something nightly for sleep, but in my opinion, as someone with chronic insomnia (without the aid of a drug), it is better to look forward to bedtime and get the sleep your body and mind need to be healthy than to lie awake, anxious and unable to sleep. I've taken Ambien, then Xanax, then Klonopin and now Lunesta. Periods of time in between, with no help, I had a lot of problems getting sufficient sleep and was walking the halls at night, all night. When I finally got in with a sleep specialist neurologist, she made it clear that we all need sleep and if we need help, we do. I also tried CBT-I and all sorts of natural things and sleep meditations but I just can't get my brain to shut down. If you don't have a sleep specialist, it might be good to get in with one and discuss your concerns. But meanwhile, be thankful for your medication if it allows to sleep peacefully, and be careful to adhere to your prescription so you don't run out.
