CO2 Toxicity rules discussion

Note: I 'm on the not so smart phone writing this which means I cant leave space between paragraphs so I'll likely do line breaks by starting a new post. CO2 toxicity is also known as hypercapnia. Early symptoms are flushed skin, full pulse, rapid breathing, shortness of breathe, irregular heart beat, muscle twitches, reduced neural activity. Mild cases have headaches confussion, and lethargy which suggests to me -10 to all abilities and -1 to IM. Severe cases involve disorientation, panic, hyperventilation, convulsions, unconsciousness, and eventually death which suggest game effects of -20 to all abilities and -2 to IM.
