This is irresponsible on your part. OP has been diagnosed by professionals and is being treated and clearly sees the difference. While high CO2 levels make a measurable difference in some tasks and its effects can be felt in crowded spaces, it seems like you're taking your pet peeve and dismissing the struggle that the OP is going through. Please try to have more sympathy.

I understand it can be difficult or even frightening to think about problems that don't have a trivially described cause, effect and solution like your proposal, but it would be a good idea to ask questions, even as simply as asking if that OP has noticed an effect, before trivializing their struggles this way
