Still mildly recovering myself....picked it up at the beginning of January, with really only minor symptoms, until about 5 days in, when I couldn't sleep. Had the wife take me to the hospital, where they diagnosed me with "some pneumonia" and unless I was sitting still, low oxygen-it would drop into the 80's upon even the slightest exertio, otherwise it was mid 90's.
they admitted me for ten days, but I never felt "sick", just kinda worn out. Sat there on my hospital bed for those ten days using Netflix and Hulu to pass the time. A course of steroids and blood thinners was pretty much all it took to get me out, although I did leave the hospital on 4 liters of O2. I spent the next three months sitting around the house waiting to be approved to return to work by my pulmonologist, and gradually improving. I'm off the supplemental O2 (although I do have a portable concentrator for as needed, and use the main concentrator with my CPAP, because....why not...and I still get winded from time to time, but, other than that, I'm back to abnormal!
good luck with the recovery, and watch your O2 levels!
