Re: CO POISIONING!
$600 in copayments? Did you even tell your doctors you may have CO poisoning? Carboxyhemoglobin can be tested for by blood or a clip on finger monitor and would confirm whether or not you really are experiencing CO poisoning and to what extent.
Months or years to get the CO out of your blood? Where are you getting this from? Carboxyhemoglobin has a half-life of 4-6 hours in the blood if breathing regular air. The use of a hyperbaric chamber can bring that down to well under an hour.
