Ha! Interesting, thanks for the info. My neurologist suggested having it on hand, but I suspect I'll end up giving it to my spouse, who actually has altitude problems.
And anyway, I figure the USADA will have a bigger problem with all the cocaine and meth they'll find in my urine.
In response to:
FYI: Acetazolamide is on the USADA banned substances list for both in and out of competition use. (It is used as a masking agent, so it is not like you'll get a direct benefit unless you are trying to hide the fact that you are also going to the local "Low-T" center that recently opened up.)
It is also a diuretic, so it may not be the best thing to use when running above tree line where bathrooms are few and far between. :-)
