Can oxygen damage be toned down

[LinkDaWolf]

Now that we've got this fancy new stamina system, maybe when you're losing oxygen, it first drains away stamina before doing the actual damage, reflecting your character's ability to hold their breath?

yeah sure, as long as it won't COMPLETELY reduce it (maybe down to a small sliver?)
my reason being that, you'll have to wait for your stamina to recharge completely before you can move and by the time it does you'll be unconscious anyway
