I have a script for Lorazepam .5 mg. I have a big presentation due next week and when I speak in front of large groups I get severe anxiety. I spoke with a pharma friend and she mentioned lots of people (including business people & students) take some sort of anti-anxiety med prior to presentations and speaking arangements. Has anyone ever tried this? how did it work? I am thinking about poping a few about an hour prior to my presentation next week. (with doing a dry run this week, i.e. just taking a few to see how they effect me) From what I understand Ativan/Lorazepam are the least powerful of the Benzo class of meds, but also very effective for anxiety associated with public speaking.
