Has anyone experienced ativan withdrawal after just a few weeks? I only take around 1-2mg a day for panic attacks. Lately I've been experiencing a lot of anxiety so have been taking it more frequently (I'd say daily for a couple of weeks). I've noticed that the next day after I take the ativan, my heart rate is elevated, I have really slow and shallow breathing, etc. I'm going to my doctor next week but I'm very worried about what's going on.
