That is not a huge dose, but if you stop it abruptly you will have some significant insomnia for a few weeks, and maybe some anxiety as well. In general, benzodiazepines (medications
that include valium, xanax, ativan... or using generic names, diazepam, alprazolam, and lorazepam, respectively. And Klonopin, or clonazepam) should be tapered and not stopped abruptly. They have a withdrawal syndrome similar to alcohol, and can cause 'DTs' including seizures that can even be fatal.
