i had to get some "real sleep" this evening. i think i'm up...

i had to close the windows for the sleep because i let the temperature fall too far to keep them open. they're back open now.

while the headache hasn't come back in full, yet, i can feel the beginnings of the tension. more importantly, i can smell the gas...

i'm about to make some eggs. i'll check back when i'm done eating. but, the experiment is this: can i resolve the headache, should it come back, by getting some fresh air into the space?
