hi.
i'm guessing you turned the gas on around the first because there appears to be a gas leak upstairs. i'm getting the smell of rotting eggs and mild headaches. this may be the cause of the migraines i was having last year.
i'm not going to be putting myself through the same literal headache this year. until this is resolved, i will be leaving the windows open to ensure a fresh air supply and turning the heat up to compensate.
