"initially, 25 mg 3xd worked pretty well for me, but the effectiveness lessened somewhat after a few weeks. then the doc changed the prescription to 25mg every 4 hrs as needed. that was ok during a bad couple of weeks, but then i began to notice myself getting irritable, which i think might have been from being so tired on it. when the anxiety got better i really noticed the irritability, which i got anyway with unmedicated anxiety. i was on it for about 3 months. i now haven&#039;t taken it for 2 days and i expect i&#039;ll only take it selectively from now on."
