One smoker told me that when he couldn't sleep, he'd smoke for as long as he was awake. That's why he always bought a pack or two of cigars, just in case . . . The same could apply to those who abuse other substances. Question is, if insomnia makes it hard for someone to kick an addiction, would taking sleeping pills be a good starting point? If they stay busy the whole day and sleep the whole night, would it be easier to overcome an addiction?
