Hi, i experienced anticipatory anxiety this week due to knowing i might have to take an elevator after foot surgery (today). I m Claustrophobic in a big way. I took .5mg of Lorazepan before bed last night (Thurs) and slept fine. Since I had extreme anxiety Mon, Tues, Wed, and Thurs., couldn t eat or sleep well, my question is, can I take another .5mg Lor. tonight without becoming addicted? Also, since this is situational anxiety, brought on by the thought of the elevator, could my anxiety subside on its own now, since surgery is over? bty, they let me walk down the stairs! :)
