Brian, I don't agree.
Lorazepam (Ativan) is a benzodiazepene.
Yes, a low dose of Ativan may calm you down for a period of time. It is apt to take 20-30 minutes or more to start working, and in the treatment of anxiety it is not as safe/effective as the breathing technique. There most certainly are risks and side effects with any benzo. I believe that the lowest dosage in which it is available is .5mg, not .05.
IMHO... not worth it.
