keithl, I've never had my eyes open during the paralyzed period. I'd always hoped that if I could open them, I'd be free from the neurological restraints. I'd hate to be able to see and still not have control.
For some reason, I've always fought it; a major battle against claustrophobic bonds.
Sometimes when I'm very physically tired, it does happen more. I can recall being very worn out with my building projects, but scared to try to sleep in because it was happening several times in quick succession.
I'd never thought about the apnea aspect. Still, obtaining a positive pressure device here would be a tad expensive.
I'll have a look at goo goo tonight. Thinking about it, I'm surprised I haven't researched it more. I suppose I choose to forget about it once it's over.
