Me too, and I've also outgrown them. I used to have the aura sometimes, but not
always. but I always smelled oranges at least 24 hours before the headache hit.

Inderal is a reasonable preventative, but it's certainly not the only
one.  A headache specialist, who usually is a neurologist but might be a
pain management subspecialist, typically will have a goal of getting you
to a point where you don't routinely have them. It would be entirely
reasonable to add some other preventive drugs, many of which are
inexpensive.

Fiorinal with codeine is a fairly old treatment, and, as you say, it is
sedating. Have you taken any of the triptan class (e.g., Imitrex and
newer, more effective/expensive drugs), which are probably more
effective and definitely nonsedating, or an ergotamine preparation,
which was the standard nonsedating treatment before the triptans.

There are also some alterative sedating "rescue" drugs that will work
much faster, several in nasal sprays that are absorbed as fast as an
injection.  I don't know if you can tolerate any downtime at work, but
some of these might break it up much more quickly. Still, the triptans
are probably the best bet unless contraindicated.

Have you been seen by a neurologist? While your mentioning an aura does
suggest classic migraine, there are some other severe headache types
that are more common in men than women.
