Method Anyone here considering using citric acid + baking soda to produce CO2 and inhale it?

I seriously consider using them to produce CO2 in a bag, inhale it and lose consciousness and then be drowned. I heard if CO2 concentration is high, loss of consciousness should be quick

Never heard of this and question it's viability

I've thought about it. I read a case about a guy succeeding that way.
