How are you being sedated?
I've had this done 3 times now for dental work and it's absolutely brilliant! I'm given triazolam throughout the procedure and basically have no memory whatsoever. I remember for a about 20 mins after the first pill (before they start the work) and it's like being nicely drunk.....you know when you've had just enough to make you feel warm and fuzzy?

Once the second pill goes under the tongue that's it....I'm out.
It's also great for the dentist as they can work quickly and easily - I've had two wisdom teeth out this way and had absolutely zero pain, swelling or bleeding afterwards. Fantastic.
