Excellent idea.  How does one get these?

I've already posted the sad story of my last cataract surgery.  My first
went without a hitch.  I can't say that it was a lot of fun, but it wasn't
bad, and I felt fine afterwards and the next day.  I should have realized
that I was in trouble for the second one when I asked my doctor how long I
would be off work and she said I could go back to work the next day.
Right before the surgery, I told the anesthesia guy that I wanted lots of
tranquilizer, and he replied, "Uh, this doctor doesn't believe in that".
I was miserable, and totally unable to stay still, which is important when
the doctor is slicing up your eye.  I was in a state of panic, and
literally terrified.  I don't know if my inability to stay still
contributed, but I was in horrible pain that night, and totally blind the
next day until the doctor reduced my IOP from 40 down to ?.  I was off
work 3 days, mostly due to mental trauma.

I don't like visiting the dentist, either.  He did a terrible job on my
first filling, partly because (as he said) it was the very hardest
location to work on and I couldn't stay still then either.  I was also
unable to keep my tongue from wandering into his way, and couldn't keep my
mouth in the correct position.  For the second filling, I self-prescribed
a tranquilizer after the receptionist told me they don't give sedatives.
I drank two glasses of whiskey before the procedure.  I'm sure my breath
wasn't too pleasant!  But the procedure went much better.  I walked to the
office, and took the day off since I knew I wouldn't be worth anything at
work anyway, even without the anesthetic (not to mention that I have 100
sick days on the books, or over four months).
