exit bag alternative

[wagner2029]

I have a two cubic meter cylinder, flow regulator, but I can't put the outlet bag on my head, is there any alternative to using a plastic bag?
I'm feeling so failed for not making it, it's all set.
I was thinking of a diving mask, I have a solenoid and a timer, I would take a few shots of zolpidem and set the timer to about 15 minutes, I would be asleep.

Yep, SCBA, SCUBA, EEBD Hoods, constant flow hoods.​

A mask connected to a flow regulator is not viable unless you use a huge flow rate (to meet the demands of inhalation) or it has a reservoir bag in the middle like Non-ReBreather masks.​
