I have a recessed light above my sink that is eating bulbs. About every

Any other suggestions?

IMHO:

Check for arcing on the bulb. You might have a bad connection with
the screwing socket.

BTW, humidity might be effecting also, so ensure the bulb is screwed
in securly.

Watch for poor contact in sockets that have previously experienced
overtightening!

I remember seeing somewhere a recommendation to not screw in a lightbulb
to an extent beyond 1/8 of a turn past the point of feeling like it made
contact. Tightening past that point supposedly risks bending down the
center contact in the socket.

Should you have a socket "damaged" by prior overtightening, then WITH
POWER OFF, preferably with the appropriate breaker off:
Pry the "cenhter contact" in the socket upwards with a screwdriver or
whatever with just enough force to make it a little higher than it was
recently, and "pat it down" with a light touch to make sure you actually
bent it a little upwards.
