can you become addicted to valium at just 1 5mg pill at night for a muscle relaxant?

yes and no it you take it when you wake up and when you want to feel high yes. but then no if you just take it like it do then no.. see valium it helps alot. but if you want to find out.. try not takeing it for severl days and if you start shaking .. like your coming off of pain pills then you are addicted to it..

I want to correct something said in the previous answer to this question.  Just because you go through withdrawal symptoms when you stop taking a drug does not mean you are addicted to it.  It simply means your body has become physically dependent on it. There's a big difference between dependency and addiction.  If you were addicted, you would be taking more than one a day.  Someone who is addicted to a drug needs ever-increasing amounts to maintain the same effect – usually a high. 

If you're concerned about continuing to take the valium, talk to your doctor about how to best discontinue it so you will have minimal withdrawal symptoms.  Good luck to you.
