Trying lorazepam

I am preparing for my first intercontinental long haul flight to Japan in a few months.

Not looking for advice. Just curious what the experience has been for anyone who has severe phobia (not anxious, but like debilitating anxiety) and tried Lorazepam. I was just prescribed a low dose to try.

For context, exposure (10 flights last year) has not helped, I’m in weekly therapy, I know the breathing techniques and statistics on safety. I am so damn scared on flights that I am totally dysfunctional and feel like I’m about to die the whole time.

Any thoughts and shared experiences are GREATLY appreciated!
