focusing yesterday wasn't going to happen; i wasn't tired, but i needed to sleep. and, now i have a list of vlogs to watch.

the headache is still there, and the windows remain open...

i'm going to get something to eat soon. i expect today will be unproductive. a migraine can knock you right out.

windows are still open, and i'm noticing the same basic cause & effect as i have previously: the headache gets a lot better if i stand beside the window for a few minutes, even if it comes back afterwards.

methane - which is my concern, not carbon monoxide - is not a poison. it can't actually hurt you, in low concentrations. what it does is smother you, so you can't breathe. but, i'm obviously getting enough oxygen. so, if i'm right about what's happening, the headaches i'm getting from the methane are basically the same thing as getting woozy after climbing a mountain: i'm just experiencing low oxygen. there aren't long term side effects, or at least won't be if the exposure is kept minimal. it's just irritating.

i'm going to try and get back to work for a few hours. i don't promise much.

i had a mild headache yesterday morning, so i stopped at about 11:00 am to lie down for a few minutes. i wasn't planning on sleeping...

i woke up in the afternoon with a brutal, splitting headache complete with blurred vision and "aura": a textbook migraine.

i didn't have a history of these up until last year, but that's more than twice, now. but, the thing is that it seems to be correlated with the tenant upstairs turning the gas off...

i remain convinced that there is a gas leak in the basement, and that there's not a lot i can do besides open the window (as an incentive to action...) until the property owner fixes it.

the headache persists. it got a little better around midnight, but it's back - with aura. i don't expect to get anything done today.

so, i'm doing a little bit of vlog editing, instead.
