By the way, I just checked the diamox I have. It's extended release so in taking it, one would not be exposed to the full 500mg dose all at once. It's in a capsule, so it's not possible to cut it in half
In 2013 my friend took the 500s and had no ill effects. I however usually only take 62.5, twice per day. At 125 mg twice per day, I had side effects.
