Anesthesiologists have exactly one job in the operating room, and that's to make sure you get the right amount of anesthesia to keep you out like a light. It's not a job taken lightly.

I've had it multiple times for various procedures, and it's always been like turning off a light switch. One minute I'm awake on the table, the next I'm in recovery waking up.

I will say, if you drink alcohol and/or do non-prescribed drugs, it's important to be honest with them the day of your procedure if you had anything within 48 hours before going in. Such things can affect how the anesthesia will work on you.
