We use it every 4-6 hours of IN WATER time.  Black et al. seemed to run 
with the idea that we take this much every day for our own grins and 
giggles.  Once this subject began it ran away with speculation on what we 
actually do.  I was far to busy at that time to interject any 
corrections.  Even on our longest dives we are around 2400 mg/24 hr 
period.  With thousands of hours of actual gas diving we have found by 
experience that this is beneficial to us.  Over the years I have attempted 
to get many different research oriented organizations to come and study us; 
the only one that has taken the time to learn from what we are doing, for 
other purposes, is the US Navy.  We are beyond what DAN is interested in by 
there own admission, at our last presentation to UHMS, most appeared to not 
believe us, those that were interested have fallen by the wayside.  The 
physiology aspect of what we do takes a back seat, unfortunately.

I was describing the drug I was NOT referring to pain during diving.

Inflammation from spending several hours at 300', moving dozens of bottles 
and several scooters around, bubble formation, etc, etc.  This is done as a 
purely preventative step.

Here you are correct.  This was mentioned to us years ago and is something 
that I have not taken the time to examine.  We do not count on this as we 
take more aggressive steps in the antioxidant area.

I do not have studies, only testimony from a handful of divers with 
thousands of hours in decompression between us.  I might try your 
suggestion of a lowered dosage on my next 300' dives, if I do, and have 
success, we might change our approach.

Dosage came from our contacts with US Navy Hyperbarics as did the 
combination of ASA.  That may have been because ASA has been used in diving 
for many years.
