Do you take it every night? Do you only take it that one time at night for sleep?
If you do not have an addictive personality, I would not worry unless you start to use this drug in any way other than as prescribed. But if I were you (and I sort of am as I also take something for sleep) I would skip the occasional night when you can allow yourself to not get good sleep. Allow yourself a restless night.
I'd also play with how you take it. For instance, try falling asleep without the drug. It's bad to become dependent on the pill to need to fall asleep. Then, have it halved by your beRABide, and take half when you wake up in the night and the brain starts racing.
I don't worry about addiction as I often test things. For instance, if I have a cold or flu bug, I do not take my sleep aid for maybe a week or 10 days. And there's never any negative effect except for not sleeping.
There are ways to watch that you do not become addicted. So many folks who write hear say the first step is moving beyond the minimum usage or as prescribed and going for more. Watch for that and try to shoot in the other direction, using it as a tool to get sleep but be willing to be inconvenienced occasionally going without it to be safe.
