But also don't eat or sniff the epoxy!

I have had similar problems in the past when I lived in a dorm room(and built there too). Some fumes will indeed make you light headed and/or dizzy, but I've never passed out - usually it was the alkiehawl that caused that.

(glad I don't do that much anymore!)
Easy solution - don't sleep where you build, or put curing adhesives somewhere else. The water thing is important too, but not the subject of this particular thread.
Chad, Hope you're ok and doing better - might want to take the building easy for a few days just in case. Give your body time to get back to normal(if possible!)
