Are you sure you didn't 'pass out' from low oxygen?

Yes, I would definitely talk to your doc about this episode and ask if it might be advisable to get an oximeter so you can monitor your O2 levels if (when) something like this happens. Also find out how he wants you to handle these incidents.

This may have been notice from your MG....kinda like if you don't slow down and listen to what I need...I'm gonna knock you out!!

Christmas is/can be a hectic and stressful time - - let's try not to spend it in the hospital!

Take extra special care right now.
