I got food poisoning and ended up going to the ER last night because I lost control of my upper body. Apparently hyperventilation (while puking my guts out) can reduce the amount of CO2 in your blood stream, making your blood mildly acidic. Before I went to the hospital I was laid out on the ground, unable to control my arms which were partially bent with my hands balled into tight painful fists. Thought I was dying.

So, pro tip, if you're ever hyperventilating and your upper body gets tingly and starts to cramp up, try your hardest to regulate your breath.

Yes! That's exactly why, and it totally works! Try to regulate your breath, but use a bag to help preserve blood CO~2~ as you're doing so!
