I've moved the fan back to the bedroom, closed the windows and blinds, and I'm about to take my Lantus. I put enzymes down the drain for the second night - - it's working really well on the sink, but the tub is being resistant, although it is better. You usually treat for three days, on nights, really, as you have to go 6 hours without using them afterwards.
I have a headache, for which I will take some ibuprofen before I lie down. But I hope I can sleep tonight.
