Thanks all - the Allegra, and Sudafed seems to be helping - I was able
to clear my ears yesterday and today.  I also broke down and turned on
the AC - at least for this week.  It still gets cool at night - but
thought closing everything up my help clear the allergens from the house.

I haven't had much luck with Flonase.

There are distinct psychological and physical issues with long term
use of Sudafed.  Besides the problems with it possibly resulting in a
reverse squeeze or eustacion tube blockage and resultant ear problems.

As with most medications, there is little/no research on their effects
outside of "normal" life.  DAN has done some studies (more like
survies) of Sudafed, and I believe that's where I got the above
information.  My doc recommends not using it for more than 4 days, due
to cardiovascular issues.  Cardiac arrythmia is not a nice thing to
have anywhere, never mind at 90 ft.

I still think his best answer is to talk to someone who knows what
they are talking about.  My medical opinions are worth about what he
pays for them.

They mentioned it in the enriched air class I just took.  But the
concern was mostly with the overall effects of the body and diving.

I've never heard of any offgassing concerns.  The concerns I've read
have been with the vasoconstriction effects of Sudafed and other
systemic decongestants (including Flonase).
While generally considered safe for diving, the concern centers around
increased susceptibility to O2 tox.  Perhaps not an issue on air until
you get below 130, but certainly an issue with nitrox.
They also cause an increase in heart rate, which will lead to
increased gas consumption... somewhat mitigated by the environment in
Coz.

The concerns over non-systemic nasal sprays, other than pure saline,
is in the rebound effect.  Afrin in particular is quite effective, and
also QUITE "addictive".  Do a Google for Afrin addiction and read some
real horror stories.
