Have 1mg klonopin (clonazepam) take as needed for anxiety. rarely take, having hard times, if i take 3-4 days a week, will i have withdrawal symptoms on off days?

Probably not: The GABA receptors that are effected by clonazepam (Klonipin) take about two weeks to change enough to induce dependence and your sporadic use gives you a "holiday" between doses. However, do not use more than prescribed. Benzodiazepine (type of med Klonipin belong to) can have potentially life threatening withdrawal. Try to stick with twice a day and taper when you stop using it.
