Full anesthesia - yeah, not an option, you need to be awake. Something milder - it could be an option (depending on the state, maybe? not sure, mine was done in WA).

Neither me nor my friends (all of us who got lasik) asked for it, but my clinic gave me valium, and my friends’ clinic gave them xanax shortly before the procedure.

Tangential sidenote: that was nearly 8 years ago, and I am absolutely glad I got it done.

Noted! I'm in the UK and nobody mentioned anything. Maybe I'll ask! I'd love to not have glasses even if it was just some of the time.
