Positioning and angle when using the exit bag

[Sixfeetunder]

I've heard that you're not supposed to lie down, but I'm worried about doing it in a chair and falling over. What position is someone supposed to be in? I considered maybe doing it in a bath tub with my head resting against the side, so I'll be propped up and won't make a crashing sound or anything when losing consciousness (I'm short enough that I can get away with doing it without bending my knees or anything). The other one I considered was doing it on the sofa in the hotel room (if there is one), same kind of position. My head and upper back would be propped up against the arms, and if there is a sofa bed, maybe lying down on it and being up at nearly a 90 degree angle. Would any of those work?

Thanks in advance.

If you have a straight backed chair you can use one or two belts/piece of rope to strap yourself into the chair.
Bath tube looks good too, as long as there is no risk to pull and dislodge the pipe.
We should remember body reflexes have been observed, But we are not equal in one case it can be just few jerks and twitches,
but someone else can experience convulsions; we need to be prepared for this too.
