answer:Benadryl is not. “The sleep inducing dose is 50 milligrams taken before bed.” “Another precaution relates to whether or not this drug is habit forming. While some people think they can become addicted to Benadryl, in all truthfulness it isn’t an addiction that is created, but more of a emotional dependency. What might happen is that if you take the drug repeatedly for long periods of time, you can become dependent on it, but it doesn’t appear to be a physical addiction. Depending on the length of time you have taken this medicine, it could take a few weeks before you are able to completely stop taking it. If you have taken it for a long time and you want to stop, it’s probably best to reduce the amount you take by slowly weaning yourself so you won’t feel the effects as dramatically.” Source
