I've been on it for 1 1/2 years. It helped for a long time, over a year or so. Greatly helped my panic attacks, claustrophobia and agoraphobia. Lately though I notice that I'm becoming claustrophic again but not to the point of panic...yet. Definitely vivid dreams, worse lately. I'm planning to get to my doc and make a change but just haven't done it. All in all it's been good while it lasted.
