light anesthesia
"My dentist doesn't use sedation so he prescribed 2mg lorazepam the night before, 1 in the morning and 1 an hour before my tooth extractions!! It worked wonders. I'm terrified of dentists by the way. I also was prescribed this same dosing for a closed machine MRI, it was very effective. I also use 1 mg for anxiety (panic attacks). It is a bit less effective - I'd give it a 7 out of 10 for that use."
