me and the cat are fine though, i dont know how he'd be poisoned with carbon monoxide? we have detectors for those and they never went off....he was in a seperate room of the house, with the doors closed with the cat, i breathed most of it in when i was doing it....the cats acting fine, and last night i got down to floor level to smell and it was fine...wouldnt I be sick too?

The label has instructions on how to use it for the future...
It is almost impossible that your b/f's symptoms are related to the oaint this far removed and with immediate fresh air. Headaches after this long should be seen by a physician. Tell them about the paint and the timing as well as dose and timing of the tylenol.
