Good article. Thanks for posting it.

I note the article recommends Acetazolamide (Diamox) 125 mg every 12 hours, but more recently, people have been using half that dose. The most recent date in the bibliography is 7 years ago. I wonder if Hackett has done any more recent work on trying the lower dosage.

I see he includes Tadalafil and Sildenafil as preventive drugs, too. Along with my Diamox, I should try taking some of that on my next high altitude backpack.
