I have chronic insomnia, should I take sleeping pills? Did they help you?

I have sleep maintainance problems and sometimes sleep onset problems. I have stopped taking herbal remedies they sometimes help but they have not stopped my sleep problems. Im thinking about taking phamacuticals but Im worried about side effects such as addiction and tolerance. MAybe they will only help in the short term and my insomnia will rebound. Should I take them? Did they help you at all?
