Method BBQ Carbon Monoxide CTB

[Sigh_Sigh_Sigh]

How effective would it be to seal all the vents, door / window frames in my bedroom and light a charcoal BBQ as I go to sleep I'd imagine the carbon monoxide would build up and take me into a constant sleep I'd never wake from?

It could. It may not, too. Anyone else in your household? That would be really dangerous for them. I suggest you read more on the CO method. There's more to it than just lighting a few coals and hanging out in a room with the lit charcoal.
